-## Design goals
-
-There are myriads of [JSON](https://json.org) libraries out there, and each may even have its reason to exist. Our class had these design goals:
-
-- **Intuitive syntax**. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the [examples below](#examples) and you'll know what I mean.
-
-- **Trivial integration**. Our whole code consists of a single header file [`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp). That's it. No library, no subproject, no dependencies, no complex build system. The class is written in vanilla C++11. All in all, everything should require no adjustment of your compiler flags or project settings.
-
-- **Serious testing**. Our class is heavily [unit-tested](https://github.com/nlohmann/json/tree/develop/test/src) and covers [100%](https://coveralls.io/r/nlohmann/json) of the code, including all exceptional behavior. Furthermore, we checked with [Valgrind](https://valgrind.org) and the [Clang Sanitizers](https://clang.llvm.org/docs/index.html) that there are no memory leaks. [Google OSS-Fuzz](https://github.com/google/oss-fuzz/tree/master/projects/json) additionally runs fuzz tests against all parsers 24/7, effectively executing billions of tests so far. To maintain high quality, the project is following the [Core Infrastructure Initiative (CII) best practices](https://bestpractices.coreinfrastructure.org/projects/289).
-
-Other aspects were not so important to us:
-
-- **Memory efficiency**. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: `std::string` for strings, `int64_t`, `uint64_t` or `double` for numbers, `std::map` for objects, `std::vector` for arrays, and `bool` for Booleans. However, you can template the generalized class `basic_json` to your needs.
-
-- **Speed**. There are certainly [faster JSON libraries](https://github.com/miloyip/nativejson-benchmark#parsing-time) out there. However, if your goal is to speed up your development by adding JSON support with a single header, then this library is the way to go. If you know how to use a `std::vector` or `std::map`, you are already set.

-
-## Examples
-
-Beside the examples below, you may want to check the [documentation](https://nlohmann.github.io/json/) where each function contains a separate code example (e.g., check out [`emplace()`](https://nlohmann.github.io/json/api/basic_json/emplace/)). All [example files](https://github.com/nlohmann/json/tree/develop/doc/examples) can be compiled and executed on their own (e.g., file [emplace.cpp](https://github.com/nlohmann/json/blob/develop/doc/examples/emplace.cpp)).
-
-### JSON as first-class data type
-
-Here are some examples to give you an idea how to use the class.
-
-Assume you want to create the JSON object
-
-```json
-{
-  "pi": 3.141,
-  "happy": true,
-  "name": "Niels",
-  "nothing": null,
-  "answer": {
-    "everything": 42
-  },
-  "list": [1, 0, 2],
-  "object": {
-    "currency": "USD",
-    "value": 42.99
-  }
-}
-```
-
-With this library, you could write:
-
-```cpp
-// create an empty structure (null)
-json j;
-
-// add a number that is stored as double (note the implicit conversion of j to an object)
-j["pi"] = 3.141;
-
-// add a Boolean that is stored as bool
-j["happy"] = true;
-
-// add a string that is stored as std::string
-j["name"] = "Niels";
-
-// add another null object by passing nullptr
-j["nothing"] = nullptr;
-
-// add an object inside the object
-j["answer"]["everything"] = 42;
-
-// add an array that is stored as std::vector (using an initializer list)
-j["list"] = { 1, 0, 2 };
-
-// add another object (using an initializer list of pairs)
-j["object"] = { {"currency", "USD"}, {"value", 42.99} };
-
-// instead, you could also write (which looks very similar to the JSON above)
-json j2 = {
-  {"pi", 3.141},
-  {"happy", true},
-  {"name", "Niels"},
-  {"nothing", nullptr},
-  {"answer", {
-    {"everything", 42}
-  }},
-  {"list", {1, 0, 2}},
-  {"object", {
-    {"currency", "USD"},
-    {"value", 42.99}
-  }}
-};
-```
-
-Note that in all these cases, you never need to "tell" the compiler which JSON value type you want to use. If you want to be explicit or express some edge cases, the functions [`json::array()`](https://nlohmann.github.io/json/api/basic_json/array/) and [`json::object()`](https://nlohmann.github.io/json/api/basic_json/object/) will help:
-
-```cpp
-// a way to express the empty array []
-json empty_array_explicit = json::array();
-
-// ways to express the empty object {}
-json empty_object_implicit = json({});
-json empty_object_explicit = json::object();
-
-// a way to express an _array_ of key/value pairs [["currency", "USD"], ["value", 42.99]]
-json array_not_object = json::array({ {"currency", "USD"}, {"value", 42.99} });
-```
-
-### Serialization / Deserialization
-
-#### To/from strings
-
-You can create a JSON value (deserialization) by appending `_json` to a string literal:
-
-```cpp
-// create object from string literal
-json j = "{ \"happy\": true, \"pi\": 3.141 }"_json;
-
-// or even nicer with a raw string literal
-auto j2 = R"(
-  {
-    "happy": true,
-    "pi": 3.141
-  }
-)"_json;
-```
-
-Note that without appending the `_json` suffix, the passed string literal is not parsed, but just used as JSON string value. That is, `json j = "{ \"happy\": true, \"pi\": 3.141 }"` would just store the string `"{ "happy": true, "pi": 3.141 }"` rather than parsing the actual object.
-
-The above example can also be expressed explicitly using [`json::parse()`](https://nlohmann.github.io/json/api/basic_json/parse/):
-
-```cpp
-// parse explicitly
-auto j3 = json::parse(R"({"happy": true, "pi": 3.141})");
-```
-
-You can also get a string representation of a JSON value (serialize):
-
-```cpp
-// explicit conversion to string
-std::string s = j.dump();    // {"happy":true,"pi":3.141}
-
-// serialization with pretty printing
-// pass in the amount of spaces to indent
-std::cout << j.dump(4) << std::endl;
-// {
-//     "happy": true,
-//     "pi": 3.141
-// }
-```
-
-Note the difference between serialization and assignment:
-
-```cpp
-// store a string in a JSON value
-json j_string = "this is a string";
-
-// retrieve the string value
-auto cpp_string = j_string.get<std::string>();
-// retrieve the string value (alternative when an variable already exists)
-std::string cpp_string2;
-j_string.get_to(cpp_string2);
-
-// retrieve the serialized value (explicit JSON serialization)
-std::string serialized_string = j_string.dump();
-
-// output of original string
-std::cout << cpp_string << " == " << cpp_string2 << " == " << j_string.get<std::string>() << '\n';
-// output of serialized value
-std::cout << j_string << " == " << serialized_string << std::endl;
-```
-
-[`.dump()`](https://nlohmann.github.io/json/api/basic_json/dump/) returns the originally stored string value.
-
-Note the library only supports UTF-8. When you store strings with different encodings in the library, calling [`dump()`](https://nlohmann.github.io/json/api/basic_json/dump/) may throw an exception unless `json::error_handler_t::replace` or `json::error_handler_t::ignore` are used as error handlers.
-
-#### To/from streams (e.g. files, string streams)
-
-You can also use streams to serialize and deserialize:
-
-```cpp
-// deserialize from standard input
-json j;
-std::cin >> j;
-
-// serialize to standard output
-std::cout << j;
-
-// the setw manipulator was overloaded to set the indentation for pretty printing
-std::cout << std::setw(4) << j << std::endl;
-```
-
-These operators work for any subclasses of `std::istream` or `std::ostream`. Here is the same example with files:
-
-```cpp
-// read a JSON file
-std::ifstream i("file.json");
-json j;
-i >> j;
-
-// write prettified JSON to another file
-std::ofstream o("pretty.json");
-o << std::setw(4) << j << std::endl;
-```
-
-Please note that setting the exception bit for `failbit` is inappropriate for this use case. It will result in program termination due to the `noexcept` specifier in use.
-
-#### Read from iterator range
-
-You can also parse JSON from an iterator range; that is, from any container accessible by iterators whose `value_type` is an integral type of 1, 2 or 4 bytes, which will be interpreted as UTF-8, UTF-16 and UTF-32 respectively. For instance, a `std::vector<std::uint8_t>`, or a `std::list<std::uint16_t>`:
-
-```cpp
-std::vector<std::uint8_t> v = {'t', 'r', 'u', 'e'};
-json j = json::parse(v.begin(), v.end());
-```
-
-You may leave the iterators for the range [begin, end):
-
-```cpp
-std::vector<std::uint8_t> v = {'t', 'r', 'u', 'e'};
-json j = json::parse(v);
-```
-
-#### Custom data source
-
-Since the parse function accepts arbitrary iterator ranges, you can provide your own data sources by implementing the `LegacyInputIterator` concept.
-
-```cpp
-struct MyContainer {
-  void advance();
-  const char& get_current();
-};
-
-struct MyIterator {
-    using difference_type = std::ptrdiff_t;
-    using value_type = char;
-    using pointer = const char*;
-    using reference = const char&;
-    using iterator_category = std::input_iterator_tag;
-
-    MyIterator& operator++() {
-        MyContainer.advance();
-        return *this;
-    }
-
-    bool operator!=(const MyIterator& rhs) const {
-        return rhs.target != target;
-    }
-
-    reference operator*() const {
-        return target.get_current();
-    }
-
-    MyContainer* target = nullptr;
-};
-
-MyIterator begin(MyContainer& tgt) {
-    return MyIterator{&tgt};
-}
-
-MyIterator end(const MyContainer&) {
-    return {};
-}
-
-void foo() {
-    MyContainer c;
-    json j = json::parse(c);
-}
-```
-
-#### SAX interface
-
-The library uses a SAX-like interface with the following functions:
-
-```cpp
-// called when null is parsed
-bool null();
-
-// called when a boolean is parsed; value is passed
-bool boolean(bool val);
-
-// called when a signed or unsigned integer number is parsed; value is passed
-bool number_integer(number_integer_t val);
-bool number_unsigned(number_unsigned_t val);
-
-// called when a floating-point number is parsed; value and original string is passed
-bool number_float(number_float_t val, const string_t& s);
-
-// called when a string is parsed; value is passed and can be safely moved away
-bool string(string_t& val);
-// called when a binary value is parsed; value is passed and can be safely moved away
-bool binary(binary_t& val);
-
-// called when an object or array begins or ends, resp. The number of elements is passed (or -1 if not known)
-bool start_object(std::size_t elements);
-bool end_object();
-bool start_array(std::size_t elements);
-bool end_array();
-// called when an object key is parsed; value is passed and can be safely moved away
-bool key(string_t& val);
-
-// called when a parse error occurs; byte position, the last token, and an exception is passed
-bool parse_error(std::size_t position, const std::string& last_token, const detail::exception& ex);
-```
-
-The return value of each function determines whether parsing should proceed.
-
-To implement your own SAX handler, proceed as follows:
-
-1. Implement the SAX interface in a class. You can use class `nlohmann::json_sax<json>` as base class, but you can also use any class where the functions described above are implemented and public.
-2. Create an object of your SAX interface class, e.g. `my_sax`.
-3. Call `bool json::sax_parse(input, &my_sax)`; where the first parameter can be any input like a string or an input stream and the second parameter is a pointer to your SAX interface.
-
-Note the `sax_parse` function only returns a `bool` indicating the result of the last executed SAX event. It does not return a  `json` value - it is up to you to decide what to do with the SAX events. Furthermore, no exceptions are thrown in case of a parse error - it is up to you what to do with the exception object passed to your `parse_error` implementation. Internally, the SAX interface is used for the DOM parser (class `json_sax_dom_parser`) as well as the acceptor (`json_sax_acceptor`), see file [`json_sax.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/detail/input/json_sax.hpp).
-
-### STL-like access
-
-We designed the JSON class to behave just like an STL container. In fact, it satisfies the [**ReversibleContainer**](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer) requirement.
-
-```cpp
-// create an array using push_back
-json j;
-j.push_back("foo");
-j.push_back(1);
-j.push_back(true);
-
-// also use emplace_back
-j.emplace_back(1.78);
-
-// iterate the array
-for (json::iterator it = j.begin(); it != j.end(); ++it) {
-  std::cout << *it << '\n';
-}
-
-// range-based for
-for (auto& element : j) {
-  std::cout << element << '\n';
-}
-
-// getter/setter
-const auto tmp = j[0].get<std::string>();
-j[1] = 42;
-bool foo = j.at(2);
-
-// comparison
-j == R"(["foo", 1, true, 1.78])"_json;  // true
-
-// other stuff
-j.size();     // 4 entries
-j.empty();    // false
-j.type();     // json::value_t::array
-j.clear();    // the array is empty again
-
-// convenience type checkers
-j.is_null();
-j.is_boolean();
-j.is_number();
-j.is_object();
-j.is_array();
-j.is_string();
-
-// create an object
-json o;
-o["foo"] = 23;
-o["bar"] = false;
-o["baz"] = 3.141;
-
-// also use emplace
-o.emplace("weather", "sunny");
-
-// special iterator member functions for objects
-for (json::iterator it = o.begin(); it != o.end(); ++it) {
-  std::cout << it.key() << " : " << it.value() << "\n";
-}
-
-// the same code as range for
-for (auto& el : o.items()) {
-  std::cout << el.key() << " : " << el.value() << "\n";
-}
-
-// even easier with structured bindings (C++17)
-for (auto& [key, value] : o.items()) {
-  std::cout << key << " : " << value << "\n";
-}
-
-// find an entry
-if (o.contains("foo")) {
-  // there is an entry with key "foo"
-}
-
-// or via find and an iterator
-if (o.find("foo") != o.end()) {
-  // there is an entry with key "foo"
-}
-
-// or simpler using count()
-int foo_present = o.count("foo"); // 1
-int fob_present = o.count("fob"); // 0
-
-// delete an entry
-o.erase("foo");
-```
-
-
-### Conversion from STL containers
-
-Any sequence container (`std::array`, `std::vector`, `std::deque`, `std::forward_list`, `std::list`) whose values can be used to construct JSON values (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JSON array. The same holds for similar associative containers (`std::set`, `std::multiset`, `std::unordered_set`, `std::unordered_multiset`), but in these cases the order of the elements of the array depends on how the elements are ordered in the respective STL container.
-
-```cpp
-std::vector<int> c_vector {1, 2, 3, 4};
-json j_vec(c_vector);
-// [1, 2, 3, 4]
-
-std::deque<double> c_deque {1.2, 2.3, 3.4, 5.6};
-json j_deque(c_deque);
-// [1.2, 2.3, 3.4, 5.6]
-
-std::list<bool> c_list {true, true, false, true};
-json j_list(c_list);
-// [true, true, false, true]
-
-std::forward_list<int64_t> c_flist {12345678909876, 23456789098765, 34567890987654, 45678909876543};
-json j_flist(c_flist);
-// [12345678909876, 23456789098765, 34567890987654, 45678909876543]
-
-std::array<unsigned long, 4> c_array {{1, 2, 3, 4}};
-json j_array(c_array);
-// [1, 2, 3, 4]
-
-std::set<std::string> c_set {"one", "two", "three", "four", "one"};
-json j_set(c_set); // only one entry for "one" is used
-// ["four", "one", "three", "two"]
-
-std::unordered_set<std::string> c_uset {"one", "two", "three", "four", "one"};
-json j_uset(c_uset); // only one entry for "one" is used
-// maybe ["two", "three", "four", "one"]
-
-std::multiset<std::string> c_mset {"one", "two", "one", "four"};
-json j_mset(c_mset); // both entries for "one" are used
-// maybe ["one", "two", "one", "four"]
-
-std::unordered_multiset<std::string> c_umset {"one", "two", "one", "four"};
-json j_umset(c_umset); // both entries for "one" are used
-// maybe ["one", "two", "one", "four"]
-```
-
-Likewise, any associative key-value containers (`std::map`, `std::multimap`, `std::unordered_map`, `std::unordered_multimap`) whose keys can construct an `std::string` and whose values can be used to construct JSON values (see examples above) can be used to create a JSON object. Note that in case of multimaps only one key is used in the JSON object and the value depends on the internal order of the STL container.
-
-```cpp
-std::map<std::string, int> c_map { {"one", 1}, {"two", 2}, {"three", 3} };
-json j_map(c_map);
-// {"one": 1, "three": 3, "two": 2 }
-
-std::unordered_map<const char*, double> c_umap { {"one", 1.2}, {"two", 2.3}, {"three", 3.4} };
-json j_umap(c_umap);
-// {"one": 1.2, "two": 2.3, "three": 3.4}
-
-std::multimap<std::string, bool> c_mmap { {"one", true}, {"two", true}, {"three", false}, {"three", true} };
-json j_mmap(c_mmap); // only one entry for key "three" is used
-// maybe {"one": true, "two": true, "three": true}
-
-std::unordered_multimap<std::string, bool> c_ummap { {"one", true}, {"two", true}, {"three", false}, {"three", true} };
-json j_ummap(c_ummap); // only one entry for key "three" is used
-// maybe {"one": true, "two": true, "three": true}
-```
-
-### JSON Pointer and JSON Patch
-
-The library supports **JSON Pointer** ([RFC 6901](https://tools.ietf.org/html/rfc6901)) as alternative means to address structured values. On top of this, **JSON Patch** ([RFC 6902](https://tools.ietf.org/html/rfc6902)) allows to describe differences between two JSON values - effectively allowing patch and diff operations known from Unix.
-
-```cpp
-// a JSON value
-json j_original = R"({
-  "baz": ["one", "two", "three"],
-  "foo": "bar"
-})"_json;
-
-// access members with a JSON pointer (RFC 6901)
-j_original["/baz/1"_json_pointer];
-// "two"
-
-// a JSON patch (RFC 6902)
-json j_patch = R"([
-  { "op": "replace", "path": "/baz", "value": "boo" },
-  { "op": "add", "path": "/hello", "value": ["world"] },
-  { "op": "remove", "path": "/foo"}
-])"_json;
-
-// apply the patch
-json j_result = j_original.patch(j_patch);
-// {
-//    "baz": "boo",
-//    "hello": ["world"]
-// }
-
-// calculate a JSON patch from two JSON values
-json::diff(j_result, j_original);
-// [
-//   { "op":" replace", "path": "/baz", "value": ["one", "two", "three"] },
-//   { "op": "remove","path": "/hello" },
-//   { "op": "add", "path": "/foo", "value": "bar" }
-// ]
-```
-
-### JSON Merge Patch
-
-The library supports **JSON Merge Patch** ([RFC 7386](https://tools.ietf.org/html/rfc7386)) as a patch format. Instead of using JSON Pointer (see above) to specify values to be manipulated, it describes the changes using a syntax that closely mimics the document being modified.
-
-```cpp
-// a JSON value
-json j_document = R"({
-  "a": "b",
-  "c": {
-    "d": "e",
-    "f": "g"
-  }
-})"_json;
-
-// a patch
-json j_patch = R"({
-  "a":"z",
-  "c": {
-    "f": null
-  }
-})"_json;
-
-// apply the patch
-j_document.merge_patch(j_patch);
-// {
-//  "a": "z",
-//  "c": {
-//    "d": "e"
-//  }
-// }
-```
-
-### Implicit conversions
-
-Supported types can be implicitly converted to JSON values.
-
-It is recommended to **NOT USE** implicit conversions **FROM** a JSON value.
-You can find more details about this recommendation [here](https://www.github.com/nlohmann/json/issues/958).
-You can switch off implicit conversions by defining `JSON_USE_IMPLICIT_CONVERSIONS` to `0` before including the `json.hpp` header. When using CMake, you can also achieve this by setting the option `JSON_ImplicitConversions` to `OFF`.
-
-```cpp
-// strings
-std::string s1 = "Hello, world!";
-json js = s1;
-auto s2 = js.get<std::string>();
-// NOT RECOMMENDED
-std::string s3 = js;
-std::string s4;
-s4 = js;
-
-// Booleans
-bool b1 = true;
-json jb = b1;
-auto b2 = jb.get<bool>();
-// NOT RECOMMENDED
-bool b3 = jb;
-bool b4;
-b4 = jb;
-
-// numbers
-int i = 42;
-json jn = i;
-auto f = jn.get<double>();
-// NOT RECOMMENDED
-double f2 = jb;
-double f3;
-f3 = jb;
-
-// etc.
-```
-
-Note that `char` types are not automatically converted to JSON strings, but to integer numbers. A conversion to a string must be specified explicitly:
-
-```cpp
-char ch = 'A';                       // ASCII value 65
-json j_default = ch;                 // stores integer number 65
-json j_string = std::string(1, ch);  // stores string "A"
-```
-
-### Arbitrary types conversions
-
-Every type can be serialized in JSON, not just STL containers and scalar types. Usually, you would do something along those lines:
-
-```cpp
-namespace ns {
-    // a simple struct to model a person
-    struct person {
-        std::string name;
-        std::string address;
-        int age;
-    };
-}
-
-ns::person p = {"Ned Flanders", "744 Evergreen Terrace", 60};
-
-// convert to JSON: copy each value into the JSON object
-json j;
-j["name"] = p.name;
-j["address"] = p.address;
-j["age"] = p.age;
-
-// ...
-
-// convert from JSON: copy each value from the JSON object
-ns::person p {
-    j["name"].get<std::string>(),
-    j["address"].get<std::string>(),
-    j["age"].get<int>()
-};
-```
-
-It works, but that's quite a lot of boilerplate... Fortunately, there's a better way:
-
-```cpp
-// create a person
-ns::person p {"Ned Flanders", "744 Evergreen Terrace", 60};
-
-// conversion: person -> json
-json j = p;
-
-std::cout << j << std::endl;
-// {"address":"744 Evergreen Terrace","age":60,"name":"Ned Flanders"}
-
-// conversion: json -> person
-auto p2 = j.get<ns::person>();
-
-// that's it
-assert(p == p2);
-```
-
-#### Basic usage
-
-To make this work with one of your types, you only need to provide two functions:
-
-```cpp
-using json = nlohmann::json;
-
-namespace ns {
-    void to_json(json& j, const person& p) {
-        j = json{{"name", p.name}, {"address", p.address}, {"age", p.age}};
-    }
-
-    void from_json(const json& j, person& p) {
-        j.at("name").get_to(p.name);
-        j.at("address").get_to(p.address);
-        j.at("age").get_to(p.age);
-    }
-} // namespace ns
-```
-
-That's all! When calling the `json` constructor with your type, your custom `to_json` method will be automatically called.
-Likewise, when calling `get<your_type>()` or `get_to(your_type&)`, the `from_json` method will be called.
-
-Some important things:
-
-* Those methods **MUST** be in your type's namespace (which can be the global namespace), or the library will not be able to locate them (in this example, they are in namespace `ns`, where `person` is defined).
-* Those methods **MUST** be available (e.g., proper headers must be included) everywhere you use these conversions. Look at [issue 1108](https://github.com/nlohmann/json/issues/1108) for errors that may occur otherwise.
-* When using `get<your_type>()`, `your_type` **MUST** be [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible). (There is a way to bypass this requirement described later.)
-* In function `from_json`, use function [`at()`](https://nlohmann.github.io/json/api/basic_json/at/) to access the object values rather than `operator[]`. In case a key does not exist, `at` throws an exception that you can handle, whereas `operator[]` exhibits undefined behavior.
-* You do not need to add serializers or deserializers for STL types like `std::vector`: the library already implements these.
-
-#### Simplify your life with macros
-
-If you just want to serialize/deserialize some structs, the `to_json`/`from_json` functions can be a lot of boilerplate.
-
-There are two macros to make your life easier as long as you (1) want to use a JSON object as serialization and (2) want to use the member variable names as object keys in that object:
-
-- `NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE(name, member1, member2, ...)` is to be defined inside of the namespace of the class/struct to create code for.
-- `NLOHMANN_DEFINE_TYPE_INTRUSIVE(name, member1, member2, ...)` is to be defined inside of the class/struct to create code for. This macro can also access private members.
-
-In both macros, the first parameter is the name of the class/struct, and all remaining parameters name the members.
-
-##### Examples
-
-The `to_json`/`from_json` functions for the `person` struct above can be created with:
-
-```cpp
-namespace ns {
-    NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE(person, name, address, age)
-}
-```
-
-Here is an example with private members, where `NLOHMANN_DEFINE_TYPE_INTRUSIVE` is needed:
-
-```cpp
-namespace ns {
-    class address {
-      private:
-        std::string street;
-        int housenumber;
-        int postcode;
-
-      public:
-        NLOHMANN_DEFINE_TYPE_INTRUSIVE(address, street, housenumber, postcode)
-    };
-}
-```
-
-#### How do I convert third-party types?
-
-This requires a bit more advanced technique. But first, let's see how this conversion mechanism works:
-
-The library uses **JSON Serializers** to convert types to json.
-The default serializer for `nlohmann::json` is `nlohmann::adl_serializer` (ADL means [Argument-Dependent Lookup](https://en.cppreference.com/w/cpp/language/adl)).
-
-It is implemented like this (simplified):
-
-```cpp
-template <typename T>
-struct adl_serializer {
-    static void to_json(json& j, const T& value) {
-        // calls the "to_json" method in T's namespace
-    }
-
-    static void from_json(const json& j, T& value) {
-        // same thing, but with the "from_json" method
-    }
-};
-```
-
-This serializer works fine when you have control over the type's namespace. However, what about `boost::optional` or `std::filesystem::path` (C++17)? Hijacking the `boost` namespace is pretty bad, and it's illegal to add something other than template specializations to `std`...
-
-To solve this, you need to add a specialization of `adl_serializer` to the `nlohmann` namespace, here's an example:
-
-```cpp
-// partial specialization (full specialization works too)
-namespace nlohmann {
-    template <typename T>
-    struct adl_serializer<boost::optional<T>> {
-        static void to_json(json& j, const boost::optional<T>& opt) {
-            if (opt == boost::none) {
-                j = nullptr;
-            } else {
-              j = *opt; // this will call adl_serializer<T>::to_json which will
-                        // find the free function to_json in T's namespace!
-            }
-        }
-
-        static void from_json(const json& j, boost::optional<T>& opt) {
-            if (j.is_null()) {
-                opt = boost::none;
-            } else {
-                opt = j.get<T>(); // same as above, but with
-                                  // adl_serializer<T>::from_json
-            }
-        }
-    };
-}
-```
-
-#### How can I use `get()` for non-default constructible/non-copyable types?
-
-There is a way, if your type is [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible). You will need to specialize the `adl_serializer` as well, but with a special `from_json` overload:
-
-```cpp
-struct move_only_type {
-    move_only_type() = delete;
-    move_only_type(int ii): i(ii) {}
-    move_only_type(const move_only_type&) = delete;
-    move_only_type(move_only_type&&) = default;
-
-    int i;
-};
-
-namespace nlohmann {
-    template <>
-    struct adl_serializer<move_only_type> {
-        // note: the return type is no longer 'void', and the method only takes
-        // one argument
-        static move_only_type from_json(const json& j) {
-            return {j.get<int>()};
-        }
-
-        // Here's the catch! You must provide a to_json method! Otherwise you
-        // will not be able to convert move_only_type to json, since you fully
-        // specialized adl_serializer on that type
-        static void to_json(json& j, move_only_type t) {
-            j = t.i;
-        }
-    };
-}
-```
-
-#### Can I write my own serializer? (Advanced use)
-
-Yes. You might want to take a look at [`unit-udt.cpp`](https://github.com/nlohmann/json/blob/develop/test/src/unit-udt.cpp) in the test suite, to see a few examples.
-
-If you write your own serializer, you'll need to do a few things:
-
-- use a different `basic_json` alias than `nlohmann::json` (the last template parameter of `basic_json` is the `JSONSerializer`)
-- use your `basic_json` alias (or a template parameter) in all your `to_json`/`from_json` methods
-- use `nlohmann::to_json` and `nlohmann::from_json` when you need ADL
-
-Here is an example, without simplifications, that only accepts types with a size <= 32, and uses ADL.
-
-```cpp
-// You should use void as a second template argument
-// if you don't need compile-time checks on T
-template<typename T, typename SFINAE = typename std::enable_if<sizeof(T) <= 32>::type>
-struct less_than_32_serializer {
-    template <typename BasicJsonType>
-    static void to_json(BasicJsonType& j, T value) {
-        // we want to use ADL, and call the correct to_json overload
-        using nlohmann::to_json; // this method is called by adl_serializer,
-                                 // this is where the magic happens
-        to_json(j, value);
-    }
-
-    template <typename BasicJsonType>
-    static void from_json(const BasicJsonType& j, T& value) {
-        // same thing here
-        using nlohmann::from_json;
-        from_json(j, value);
-    }
-};
-```
-
-Be **very** careful when reimplementing your serializer, you can stack overflow if you don't pay attention:
-
-```cpp
-template <typename T, void>
-struct bad_serializer
-{
-    template <typename BasicJsonType>
-    static void to_json(BasicJsonType& j, const T& value) {
-      // this calls BasicJsonType::json_serializer<T>::to_json(j, value);
-      // if BasicJsonType::json_serializer == bad_serializer ... oops!
-      j = value;
-    }
-
-    template <typename BasicJsonType>
-    static void to_json(const BasicJsonType& j, T& value) {
-      // this calls BasicJsonType::json_serializer<T>::from_json(j, value);
-      // if BasicJsonType::json_serializer == bad_serializer ... oops!
-      value = j.template get<T>(); // oops!
-    }
-};
-```
-
-### Specializing enum conversion
-
-By default, enum values are serialized to JSON as integers. In some cases this could result in undesired behavior. If an enum is modified or re-ordered after data has been serialized to JSON, the later de-serialized JSON data may be undefined or a different enum value than was originally intended.
-
-It is possible to more precisely specify how a given enum is mapped to and from JSON as shown below:
-
-```cpp
-// example enum type declaration
-enum TaskState {
-    TS_STOPPED,
-    TS_RUNNING,
-    TS_COMPLETED,
-    TS_INVALID=-1,
-};
-
-// map TaskState values to JSON as strings
-NLOHMANN_JSON_SERIALIZE_ENUM( TaskState, {
-    {TS_INVALID, nullptr},
-    {TS_STOPPED, "stopped"},
-    {TS_RUNNING, "running"},
-    {TS_COMPLETED, "completed"},
-})
-```
-
-The `NLOHMANN_JSON_SERIALIZE_ENUM()` macro declares a set of `to_json()` / `from_json()` functions for type `TaskState` while avoiding repetition and boilerplate serialization code.
-
-**Usage:**
-
-```cpp
-// enum to JSON as string
-json j = TS_STOPPED;
-assert(j == "stopped");
-
-// json string to enum
-json j3 = "running";
-assert(j3.get<TaskState>() == TS_RUNNING);
-
-// undefined json value to enum (where the first map entry above is the default)
-json jPi = 3.14;
-assert(jPi.get<TaskState>() == TS_INVALID );
-```
-
-Just as in [Arbitrary Type Conversions](#arbitrary-types-conversions) above,
-- `NLOHMANN_JSON_SERIALIZE_ENUM()` MUST be declared in your enum type's namespace (which can be the global namespace), or the library will not be able to locate it and it will default to integer serialization.
-- It MUST be available (e.g., proper headers must be included) everywhere you use the conversions.
-
-Other Important points:
-- When using `get<ENUM_TYPE>()`, undefined JSON values will default to the first pair specified in your map. Select this default pair carefully.
-- If an enum or JSON value is specified more than once in your map, the first matching occurrence from the top of the map will be returned when converting to or from JSON.
-
-### Binary formats (BSON, CBOR, MessagePack, and UBJSON)
-
-Though JSON is a ubiquitous data format, it is not a very compact format suitable for data exchange, for instance over a network. Hence, the library supports [BSON](https://bsonspec.org) (Binary JSON), [CBOR](https://cbor.io) (Concise Binary Object Representation), [MessagePack](https://msgpack.org), and [UBJSON](https://ubjson.org) (Universal Binary JSON Specification) to efficiently encode JSON values to byte vectors and to decode such vectors.
-
-```cpp
-// create a JSON value
-json j = R"({"compact": true, "schema": 0})"_json;
-
-// serialize to BSON
-std::vector<std::uint8_t> v_bson = json::to_bson(j);
-
-// 0x1B, 0x00, 0x00, 0x00, 0x08, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0x00, 0x01, 0x10, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
-
-// roundtrip
-json j_from_bson = json::from_bson(v_bson);
-
-// serialize to CBOR
-std::vector<std::uint8_t> v_cbor = json::to_cbor(j);
-
-// 0xA2, 0x67, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0xF5, 0x66, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x00
-
-// roundtrip
-json j_from_cbor = json::from_cbor(v_cbor);
-
-// serialize to MessagePack
-std::vector<std::uint8_t> v_msgpack = json::to_msgpack(j);
-
-// 0x82, 0xA7, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0xC3, 0xA6, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x00
-
-// roundtrip
-json j_from_msgpack = json::from_msgpack(v_msgpack);
-
-// serialize to UBJSON
-std::vector<std::uint8_t> v_ubjson = json::to_ubjson(j);
-
-// 0x7B, 0x69, 0x07, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0x54, 0x69, 0x06, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x69, 0x00, 0x7D
-
-// roundtrip
-json j_from_ubjson = json::from_ubjson(v_ubjson);
-```
-
-The library also supports binary types from BSON, CBOR (byte strings), and MessagePack (bin, ext, fixext). They are stored by default as `std::vector<std::uint8_t>` to be processed outside of the library.
-
-```cpp
-// CBOR byte string with payload 0xCAFE
-std::vector<std::uint8_t> v = {0x42, 0xCA, 0xFE};
-
-// read value
-json j = json::from_cbor(v);
-
-// the JSON value has type binary
-j.is_binary(); // true
-
-// get reference to stored binary value
-auto& binary = j.get_binary();
-
-// the binary value has no subtype (CBOR has no binary subtypes)
-binary.has_subtype(); // false
-
-// access std::vector<std::uint8_t> member functions
-binary.size(); // 2
-binary[0]; // 0xCA
-binary[1]; // 0xFE
-
-// set subtype to 0x10
-binary.set_subtype(0x10);
-
-// serialize to MessagePack
-auto cbor = json::to_msgpack(j); // 0xD5 (fixext2), 0x10, 0xCA, 0xFE
-```
-

-## Supported compilers
-
-Though it's 2021 already, the support for C++11 is still a bit sparse. Currently, the following compilers are known to work:
-
-- GCC 4.8 - 11.0 (and possibly later)
-- Clang 3.4 - 12.0 (and possibly later)
-- Apple Clang 9.1 - 12.4 (and possibly later)
-- Intel C++ Compiler 17.0.2 (and possibly later)
-- Microsoft Visual C++ 2015 / Build Tools 14.0.25123.0 (and possibly later)
-- Microsoft Visual C++ 2017 / Build Tools 15.5.180.51428 (and possibly later)
-- Microsoft Visual C++ 2019 / Build Tools 16.3.1+1def00d3d (and possibly later)
-
-I would be happy to learn about other compilers/versions.
-
-Please note:
-
-- GCC 4.8 has a bug [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824)): multiline raw strings cannot be the arguments to macros. Don't use multiline raw strings directly in macros with this compiler.
-- Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default.

-    The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10.

-- For GCC running on MinGW or Android SDK, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`) may occur. Note this is not an issue with the code,  but rather with the compiler itself. On Android, see above to build with a newer environment.  For MinGW, please refer to [this site](https://tehsausage.com/mingw-to-string) and [this discussion](https://github.com/nlohmann/json/issues/136) for information on how to fix this bug. For Android NDK using `APP_STL := gnustl_static`, please refer to [this discussion](https://github.com/nlohmann/json/issues/219).
-
-- Unsupported versions of GCC and Clang are rejected by `#error` directives. This can be switched off by defining `JSON_SKIP_UNSUPPORTED_COMPILER_CHECK`. Note that you can expect no support in this case.

-## Integration
-
-[`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp) is the single required file in `single_include/nlohmann` or [released here](https://github.com/nlohmann/json/releases). You need to add
-
-```cpp
-#include <nlohmann/json.hpp>
-
-// for convenience
-using json = nlohmann::json;
-```
-
-to the files you want to process JSON and set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang).
-
-You can further use file [`include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/json_fwd.hpp) for forward-declarations. The installation of json_fwd.hpp (as part of cmake's install step), can be achieved by setting `-DJSON_MultipleHeaders=ON`.
-
-### CMake
-
-You can also use the `nlohmann_json::nlohmann_json` interface target in CMake.  This target populates the appropriate usage requirements for `INTERFACE_INCLUDE_DIRECTORIES` to point to the appropriate include directories and `INTERFACE_COMPILE_FEATURES` for the necessary C++11 flags.
-
-#### External
-
-To use this library from a CMake project, you can locate it directly with `find_package()` and use the namespaced imported target from the generated package configuration:
-
-```cmake
-# CMakeLists.txt
-find_package(nlohmann_json 3.2.0 REQUIRED)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-The package configuration file, `nlohmann_jsonConfig.cmake`, can be used either from an install tree or directly out of the build tree.
-
-#### Embedded
-
-To embed the library directly into an existing CMake project, place the entire source tree in a subdirectory and call `add_subdirectory()` in your `CMakeLists.txt` file:
-
-```cmake
-# Typically you don't care so much for a third party library's tests to be
-# run from your own project's code.
-set(JSON_BuildTests OFF CACHE INTERNAL "")
-
-# If you only include this third party in PRIVATE source files, you do not
-# need to install it when your main project gets installed.
-# set(JSON_Install OFF CACHE INTERNAL "")
-
-# Don't use include(nlohmann_json/CMakeLists.txt) since that carries with it
-# unintended consequences that will break the build.  It's generally
-# discouraged (although not necessarily well documented as such) to use
-# include(...) for pulling in other CMake projects anyways.
-add_subdirectory(nlohmann_json)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-##### Embedded (FetchContent)
-
-Since CMake v3.11,
-[FetchContent](https://cmake.org/cmake/help/v3.11/module/FetchContent.html) can
-be used to automatically download the repository as a dependency at configure time.
-
-Example:
-```cmake
-include(FetchContent)
-
-FetchContent_Declare(json
-  GIT_REPOSITORY https://github.com/nlohmann/json.git
-  GIT_TAG v3.7.3)
-
-FetchContent_GetProperties(json)
-if(NOT json_POPULATED)
-  FetchContent_Populate(json)
-  add_subdirectory(${json_SOURCE_DIR} ${json_BINARY_DIR} EXCLUDE_FROM_ALL)
-endif()
-
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-**Note**: The repository https://github.com/nlohmann/json download size is huge.
-It contains all the dataset used for the benchmarks. You might want to depend on
-a smaller repository. For instance, you might want to replace the URL above by
-https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent
-
-#### Supporting Both
-
-To allow your project to support either an externally supplied or an embedded JSON library, you can use a pattern akin to the following:
-
-``` cmake
-# Top level CMakeLists.txt
-project(FOO)
-...
-option(FOO_USE_EXTERNAL_JSON "Use an external JSON library" OFF)
-...
-add_subdirectory(thirdparty)
-...
-add_library(foo ...)
-...
-# Note that the namespaced target will always be available regardless of the
-# import method
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-```cmake
-# thirdparty/CMakeLists.txt
-...
-if(FOO_USE_EXTERNAL_JSON)
-  find_package(nlohmann_json 3.2.0 REQUIRED)
-else()
-  set(JSON_BuildTests OFF CACHE INTERNAL "")
-  add_subdirectory(nlohmann_json)
-endif()
-...
-```
-
-`thirdparty/nlohmann_json` is then a complete copy of this source tree.
-
-### Package Managers
-
-:beer: If you are using OS X and [Homebrew](https://brew.sh), just type `brew tap nlohmann/json` and `brew install nlohmann-json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann-json --HEAD`.
-
-If you are using the [Meson Build System](https://mesonbuild.com), add this source tree as a [meson subproject](https://mesonbuild.com/Subprojects.html#using-a-subproject). You may also use the `include.zip` published in this project's [Releases](https://github.com/nlohmann/json/releases) to reduce the size of the vendored source tree. Alternatively, you can get a wrap file by downloading it from [Meson WrapDB](https://wrapdb.mesonbuild.com/nlohmann_json), or simply use `meson wrap install nlohmann_json`. Please see the meson project for any issues regarding the packaging.
-
-The provided meson.build can also be used as an alternative to cmake for installing `nlohmann_json` system-wide in which case a pkg-config file is installed. To use it, simply have your build system require the `nlohmann_json` pkg-config dependency. In Meson, it is preferred to use the [`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than using the subproject directly.
-
-If you are using [Conan](https://www.conan.io/) to manage your dependencies, merely add [`nlohmann_json/x.y.z`](https://conan.io/center/nlohmann_json) to your `conanfile`'s requires, where `x.y.z` is the release version you want to use. Please file issues [here](https://github.com/conan-io/conan-center-index/issues) if you experience problems with the packages.
-
-If you are using [Spack](https://www.spack.io/) to manage your dependencies, you can use the [`nlohmann-json` package](https://spack.readthedocs.io/en/latest/package_list.html#nlohmann-json). Please see the [spack project](https://github.com/spack/spack) for any issues regarding the packaging.
-
-If you are using [hunter](https://github.com/cpp-pm/hunter) on your project for external dependencies, then you can use the [nlohmann_json package](https://hunter.readthedocs.io/en/latest/packages/pkg/nlohmann_json.html). Please see the hunter project for any issues regarding the packaging.
-
-If you are using [Buckaroo](https://buckaroo.pm), you can install this library's module with `buckaroo add github.com/buckaroo-pm/nlohmann-json`. Please file issues [here](https://github.com/buckaroo-pm/nlohmann-json). There is a demo repo [here](https://github.com/njlr/buckaroo-nholmann-json-example).
-
-If you are using [vcpkg](https://github.com/Microsoft/vcpkg/) on your project for external dependencies, then you can use the [nlohmann-json package](https://github.com/Microsoft/vcpkg/tree/master/ports/nlohmann-json). Please see the vcpkg project for any issues regarding the packaging.
-
-If you are using [cget](https://cget.readthedocs.io/en/latest/), you can install the latest development version with `cget install nlohmann/json`. A specific version can be installed with `cget install nlohmann/json@v3.1.0`. Also, the multiple header version can be installed by adding the `-DJSON_MultipleHeaders=ON` flag (i.e., `cget install nlohmann/json -DJSON_MultipleHeaders=ON`).
-
-If you are using [CocoaPods](https://cocoapods.org), you can use the library by adding pod `"nlohmann_json", '~>3.1.2'` to your podfile (see [an example](https://bitbucket.org/benman/nlohmann_json-cocoapod/src/master/)). Please file issues [here](https://bitbucket.org/benman/nlohmann_json-cocoapod/issues?status=new&status=open).
-
-If you are using [NuGet](https://www.nuget.org), you can use the package [nlohmann.json](https://www.nuget.org/packages/nlohmann.json/). Please check [this extensive description](https://github.com/nlohmann/json/issues/1132#issuecomment-452250255) on how to use the package. Please files issues [here](https://github.com/hnkb/nlohmann-json-nuget/issues).
-
-If you are using [conda](https://conda.io/), you can use the package [nlohmann_json](https://github.com/conda-forge/nlohmann_json-feedstock) from [conda-forge](https://conda-forge.org) executing `conda install -c conda-forge nlohmann_json`. Please file issues [here](https://github.com/conda-forge/nlohmann_json-feedstock/issues).
-
-If you are using [MSYS2](https://www.msys2.org/), your can use the [mingw-w64-nlohmann-json](https://packages.msys2.org/base/mingw-w64-nlohmann-json) package, just type `pacman -S mingw-w64-i686-nlohmann-json` or `pacman -S mingw-w64-x86_64-nlohmann-json` for installation. Please file issues [here](https://github.com/msys2/MINGW-packages/issues/new?title=%5Bnlohmann-json%5D) if you experience problems with the packages.
-
-If you are using [`build2`](https://build2.org), you can use the [`nlohmann-json`](https://cppget.org/nlohmann-json) package from the public repository https://cppget.org or directly from the [package's sources repository](https://github.com/build2-packaging/nlohmann-json). In your project's `manifest` file, just add `depends: nlohmann-json` (probably with some [version constraints](https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml#guide-add-remove-deps)). If you are not familiar with using dependencies in `build2`, [please read this introduction](https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml).
-Please file issues [here](https://github.com/build2-packaging/nlohmann-json) if you experience problems with the packages.
-
-If you are using [`wsjcpp`](https://wsjcpp.org), you can use the command `wsjcpp install "https://github.com/nlohmann/json:develop"` to get the latest version. Note you can change the branch ":develop" to an existing tag or another branch.
-
-If you are using [`CPM.cmake`](https://github.com/TheLartians/CPM.cmake), you can check this [`example`](https://github.com/TheLartians/CPM.cmake/tree/master/examples/json). After [adding CPM script](https://github.com/TheLartians/CPM.cmake#adding-cpm) to your project, implement the following snippet to your CMake:
-
-```cmake
-CPMAddPackage(
-    NAME nlohmann_json
-    GITHUB_REPOSITORY nlohmann/json
-    VERSION 3.9.1)
-```
-
-### Pkg-config
-
-If you are using bare Makefiles, you can use `pkg-config` to generate the include flags that point to where the library is installed:
-
-```sh
-pkg-config nlohmann_json --cflags
-```
-
-Users of the Meson build system will also be able to use a system wide library, which will be found by `pkg-config`:
-
-```meson
-json = dependency('nlohmann_json', required: true)
-```

Please describe your request, problem, or question as detailed as possible, and also mention the version of the library you are using as well as the version of your compiler and operating system. Opening an issue at GitHub allows other users and contributors to this library to collaborate. For instance, I have little experience with MSVC, and most issues in this regard have been solved by a growing community. If you have a look at the [closed issues](https://github.com/nlohmann/json/issues?q=is%3Aissue+is%3Aclosed), you will see that we react quite timely in most cases.

-## Projects using JSON for Modern C++
-
-The library is currently used in Apple macOS Sierra and iOS 10. I am not sure what they are using the library for, but I am happy that it runs on so many devices.
-
-
-## Notes
-
-### Character encoding
-
-The library supports **Unicode input** as follows:
-
-- Only **UTF-8** encoded input is supported which is the default encoding for JSON according to [RFC 8259](https://tools.ietf.org/html/rfc8259.html#section-8.1).
-- `std::u16string` and `std::u32string` can be parsed, assuming UTF-16 and UTF-32 encoding, respectively. These encodings are not supported when reading from files or other input containers.
-- Other encodings such as Latin-1 or ISO 8859-1 are **not** supported and will yield parse or serialization errors.
-- [Unicode noncharacters](https://www.unicode.org/faq/private_use.html#nonchar1) will not be replaced by the library.
-- Invalid surrogates (e.g., incomplete pairs such as `\uDEAD`) will yield parse errors.
-- The strings stored in the library are UTF-8 encoded. When using the default string type (`std::string`), note that its length/size functions return the number of stored bytes rather than the number of characters or glyphs.
-- When you store strings with different encodings in the library, calling [`dump()`](https://nlohmann.github.io/json/api/basic_json/dump/) may throw an exception unless `json::error_handler_t::replace` or `json::error_handler_t::ignore` are used as error handlers.
-- To store wide strings (e.g., `std::wstring`), you need to convert them to a a UTF-8 encoded `std::string` before, see [an example](https://json.nlohmann.me/home/faq/#wide-string-handling).
-
-### Comments in JSON
-
-This library does not support comments by default. It does so for three reasons:
-
-1. Comments are not part of the [JSON specification](https://tools.ietf.org/html/rfc8259). You may argue that `//` or `/* */` are allowed in JavaScript, but JSON is not JavaScript.
-2. This was not an oversight: Douglas Crockford [wrote on this](https://plus.google.com/118095276221607585885/posts/RK8qyGVaGSr) in May 2012:
-
-	> I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability.  I know that the lack of comments makes some people sad, but it shouldn't.
-
-	> Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.
-
-3. It is dangerous for interoperability if some libraries would add comment support while others don't. Please check [The Harmful Consequences of the Robustness Principle](https://tools.ietf.org/html/draft-iab-protocol-maintenance-01) on this.
-
-However, you can pass set parameter `ignore_comments` to true in the `parse` function to ignore `//` or `/* */` comments. Comments will then be treated as whitespace.
-
-### Order of object keys
-
-By default, the library does not preserve the **insertion order of object elements**. This is standards-compliant, as the [JSON standard](https://tools.ietf.org/html/rfc8259.html) defines objects as "an unordered collection of zero or more name/value pairs".
-
-If you do want to preserve the insertion order, you can try the type [`nlohmann::ordered_json`](https://github.com/nlohmann/json/issues/2179). Alternatively, you can use a more sophisticated ordered map like [`tsl::ordered_map`](https://github.com/Tessil/ordered-map) ([integration](https://github.com/nlohmann/json/issues/546#issuecomment-304447518)) or [`nlohmann::fifo_map`](https://github.com/nlohmann/fifo_map) ([integration](https://github.com/nlohmann/json/issues/485#issuecomment-333652309)).
-
-### Memory Release
-
-We checked with Valgrind and the Address Sanitizer (ASAN) that there are no memory leaks.
-
-If you find that a parsing program with this library does not release memory, please consider the following case and it maybe unrelated to this library.
-
-**Your program is compiled with glibc.** There is a tunable threshold that glibc uses to decide whether to actually return memory to the system or whether to cache it for later reuse. If in your program you make lots of small allocations and those small allocations are not a contiguous block and are presumably below the threshold, then they will not get returned to the OS.
-Here is a related issue [#1924](https://github.com/nlohmann/json/issues/1924).
-
-### Further notes
-
-- The code contains numerous debug **assertions** which can be switched off by defining the preprocessor macro `NDEBUG`, see the [documentation of `assert`](https://en.cppreference.com/w/cpp/error/assert). In particular, note [`operator[]`](https://nlohmann.github.io/json/api/basic_json/operator%5B%5D/) implements **unchecked access** for const objects: If the given key is not present, the behavior is undefined (think of a dereferenced null pointer) and yields an [assertion failure](https://github.com/nlohmann/json/issues/289) if assertions are switched on. If you are not sure whether an element in an object exists, use checked access with the [`at()` function](https://nlohmann.github.io/json/api/basic_json/at/). Furthermore, you can define `JSON_ASSERT(x)` to replace calls to `assert(x)`.
-- As the exact type of a number is not defined in the [JSON specification](https://tools.ietf.org/html/rfc8259.html), this library tries to choose the best fitting C++ number type automatically. As a result, the type `double` may be used to store numbers which may yield [**floating-point exceptions**](https://github.com/nlohmann/json/issues/181) in certain rare situations if floating-point exceptions have been unmasked in the calling code. These exceptions are not caused by the library and need to be fixed in the calling code, such as by re-masking the exceptions prior to calling library functions.
-- The code can be compiled without C++ **runtime type identification** features; that is, you can use the `-fno-rtti` compiler flag.
-- **Exceptions** are used widely within the library. They can, however, be switched off with either using the compiler flag `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION`. In this case, exceptions are replaced by `abort()` calls. You can further control this behavior by defining `JSON_THROW_USER` (overriding `throw`), `JSON_TRY_USER` (overriding `try`), and `JSON_CATCH_USER` (overriding `catch`). Note that `JSON_THROW_USER` should leave the current scope (e.g., by throwing or aborting), as continuing after it may yield undefined behavior. Note the explanatory [`what()`](https://en.cppreference.com/w/cpp/error/exception/what) string of exceptions is not available for MSVC if exceptions are disabled, see [#2824](https://github.com/nlohmann/json/discussions/2824).
-
-## Execute unit tests
-
-To compile and run the tests, you need to execute
-
-```sh
-$ mkdir build
-$ cd build
-$ cmake .. -DJSON_BuildTests=On
-$ cmake --build .
-$ ctest --output-on-failure
-```
-
-Note that during the `ctest` stage, several JSON test files are downloaded from an [external repository](https://github.com/nlohmann/json_test_data). If policies forbid downloading artifacts during testing, you can download the files yourself and pass the directory with the test files via `-DJSON_TestDataDirectory=path` to CMake. Then, no Internet connectivity is required. See [issue #2189](https://github.com/nlohmann/json/issues/2189) for more information.
-
-In case you have downloaded the library rather than checked out the code via Git, test `cmake_fetch_content_configure` will fail. Please execute `ctest -LE git_required` to skip these tests. See [issue #2189](https://github.com/nlohmann/json/issues/2189) for more information.
-
-Some tests change the installed files and hence make the whole process not reproducible. Please execute `ctest -LE not_reproducible` to skip these tests. See [issue #2324](https://github.com/nlohmann/json/issues/2324) for more information.
-
-Note you need to call `cmake -LE "not_reproducible|git_required"` to exclude both labels. See [issue #2596](https://github.com/nlohmann/json/issues/2596) for more information.
-
-As Intel compilers use unsafe floating point optimization by default, the unit tests may fail. Use flag [`/fp:precise`](https://software.intel.com/content/www/us/en/develop/documentation/cpp-compiler-developer-guide-and-reference/top/compiler-reference/compiler-options/compiler-option-details/floating-point-options/fp-model-fp.html) then.

-@brief the JSON type enumeration
-
-This enumeration collects the different JSON types. It is internally used to
-distinguish the stored values, and the functions @ref basic_json::is_null(),
-@ref basic_json::is_object(), @ref basic_json::is_array(),
-@ref basic_json::is_string(), @ref basic_json::is_boolean(),
-@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
-@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
-@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
-@ref basic_json::is_structured() rely on it.
-
-@note There are three enumeration entries (number_integer, number_unsigned, and
-number_float), because the library distinguishes these three types for numbers:
-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.
-
-@sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON
-value with the default value for a given type

-@brief general exception of the @ref basic_json class
-
-This class is an extension of `std::exception` objects with a member @a id for
-exception ids. It is used as the base class for all exceptions thrown by the
-@ref basic_json class. This class can hence be used as "wildcard" to catch
-exceptions.
-
-Subclasses:
-- @ref parse_error for exceptions indicating a parse error
-- @ref invalid_iterator for exceptions indicating errors with iterators
-- @ref type_error for exceptions indicating executing a member function with
-                  a wrong type
-- @ref out_of_range for exceptions indicating access out of the defined range
-- @ref other_error for exceptions indicating other library errors
-
-@internal
-@note To have nothrow-copy-constructible exceptions, we internally use
-      `std::runtime_error` which can cope with arbitrary-length error messages.
-      Intermediate strings are built with static functions and then passed to
-      the actual constructor.

-@brief exception indicating a parse error
-
-This exception is thrown by the library when a parse error occurs. Parse errors
-can occur during the deserialization of JSON text, CBOR, MessagePack, as well
-as when using JSON Patch.
-
-Member @a byte holds the byte index of the last read character in the input
-file.
-
-Exceptions have ids 1xx.
-
-name / id                      | example message | description
------------------------------- | --------------- | -------------------------
-json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
-json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
-json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
-json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
-json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
-json.exception.parse_error.106 | parse error: array index '01' must not begin with '0' | An array index in a JSON Pointer ([RFC 6901](https://tools.ietf.org/html/rfc6901)) may be `0` or any number without a leading `0`.
-json.exception.parse_error.107 | parse error: JSON pointer must be empty or begin with '/' - was: 'foo' | A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a `/` character.
-json.exception.parse_error.108 | parse error: escape character '~' must be followed with '0' or '1' | In a JSON Pointer, only `~0` and `~1` are valid escape sequences.
-json.exception.parse_error.109 | parse error: array index 'one' is not a number | A JSON Pointer array index must be a number.
-json.exception.parse_error.110 | parse error at 1: cannot read 2 bytes from vector | When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
-json.exception.parse_error.112 | parse error at 1: error reading CBOR; last byte: 0xF8 | Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
-json.exception.parse_error.113 | parse error at 2: expected a CBOR string; last byte: 0x98 | While parsing a map key, a value that is not a string has been read.
-json.exception.parse_error.114 | parse error: Unsupported BSON record type 0x0F | The parsing of the corresponding BSON record type is not implemented (yet).
-json.exception.parse_error.115 | parse error at byte 5: syntax error while parsing UBJSON high-precision number: invalid number text: 1A | A UBJSON high-precision number could not be parsed.
-
-@note For an input with n bytes, 1 is the index of the first character and n+1
-      is the index of the terminating null byte or the end of file. This also
-      holds true when reading a byte vector (CBOR or MessagePack).

-json.exception.invalid_iterator.201 | iterators are not compatible | The iterators passed to constructor @ref basic_json(InputIT first, InputIT last) are not compatible, meaning they do not belong to the same container. Therefore, the range (@a first, @a last) is invalid.
-json.exception.invalid_iterator.202 | iterator does not fit current value | In an erase or insert function, the passed iterator @a pos does not belong to the JSON value for which the function was called. It hence does not define a valid position for the deletion/insertion.
-json.exception.invalid_iterator.203 | iterators do not fit current value | Either iterator passed to function @ref erase(IteratorType first, IteratorType last) does not belong to the JSON value from which values shall be erased. It hence does not define a valid range to delete values from.
-json.exception.invalid_iterator.204 | iterators out of range | When an iterator range for a primitive type (number, boolean, or string) is passed to a constructor or an erase function, this range has to be exactly (@ref begin(), @ref end()), because this is the only way the single stored value is expressed. All other ranges are invalid.
-json.exception.invalid_iterator.205 | iterator out of range | When an iterator for a primitive type (number, boolean, or string) is passed to an erase function, the iterator has to be the @ref begin() iterator, because it is the only way to address the stored value. All other iterators are invalid.
-json.exception.invalid_iterator.206 | cannot construct with iterators from null | The iterators passed to constructor @ref basic_json(InputIT first, InputIT last) belong to a JSON null value and hence to not define a valid range.
-json.exception.invalid_iterator.207 | cannot use key() for non-object iterators | The key() member function can only be used on iterators belonging to a JSON object, because other types do not have a concept of a key.
-json.exception.invalid_iterator.208 | cannot use operator[] for object iterators | The operator[] to specify a concrete offset cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.209 | cannot use offsets with object iterators | The offset operators (+, -, +=, -=) cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.210 | iterators do not fit | The iterator range passed to the insert function are not compatible, meaning they do not belong to the same container. Therefore, the range (@a first, @a last) is invalid.
-json.exception.invalid_iterator.211 | passed iterators may not belong to container | The iterator range passed to the insert function must not be a subrange of the container to insert to.
-json.exception.invalid_iterator.212 | cannot compare iterators of different containers | When two iterators are compared, they must belong to the same container.
-json.exception.invalid_iterator.213 | cannot compare order of object iterators | The order of object iterators cannot be compared, because JSON objects are unordered.
-json.exception.invalid_iterator.214 | cannot get value | Cannot get value for iterator: Either the iterator belongs to a null value or it is an iterator to a primitive type (number, boolean, or string), but the iterator is different to @ref begin().

-@brief SAX implementation to create a JSON value from SAX events
-
-This class implements the @ref json_sax interface and processes the SAX events
-to create a JSON value which makes it basically a DOM parser. The structure or
-hierarchy of the JSON value is managed by the stack `ref_stack` which contains
-a pointer to the respective array or object for each recursion depth.
-
-After successful parsing, the value that is passed by reference to the
-constructor contains the parsed value.

-    This function scans a string according to Sect. 6 of RFC 8259.
-
-    The function is realized with a deterministic finite state machine derived
-    from the grammar described in RFC 8259. Starting in state "init", the
-    input is read and used to determined the next state. Only state "done"
-    accepts the number. State "error" is a trap state to model errors. In the
-    table below, "anything" means any character but the ones listed before.

-    any2     | any2     | any2     | done     | done    | done    | done     | done
-
-    The state machine is realized with one label per state (prefixed with
-    "scan_number_") and `goto` statements between them. The state machine
-    contains cycles, but any cycle can be left when EOF is read. Therefore,
-    the function is guaranteed to terminate.
-
-    During scanning, the read bytes are stored in token_buffer. This string is
-    then converted to a signed integer, an unsigned integer, or a
-    floating-point number.

-@brief a template for a bidirectional iterator for the @ref basic_json class
-This class implements a both iterators (iterator and const_iterator) for the
-@ref basic_json class.
-@note An iterator is called *initialized* when a pointer to a JSON value has
-      been set (e.g., by a constructor or a copy assignment). If the iterator is
-      default-constructed, it is *uninitialized* and most methods are undefined.
-      **The library uses assertions to detect calls on uninitialized iterators.**
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-@since version 1.0.0, simplified in version 2.0.9, change to bidirectional

-@brief a template for a reverse iterator class
-
-@tparam Base the base iterator type to reverse. Valid types are @ref
-iterator (to create @ref reverse_iterator) and @ref const_iterator (to
-create @ref const_reverse_iterator).
-
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):
-  It is possible to write to the pointed-to element (only if @a Base is
-  @ref iterator).

-@since version 1.0.0

-// The choice of (alpha,gamma) determines the size of the table and the form of

-//
-// The idea is to cut the number c * w = f * 2^e into two parts, which can be
-// processed independently: An integral part p1, and a fractional part p2:
-//
-//      f * 2^e = ( (f div 2^-e) * 2^-e + (f mod 2^-e) ) * 2^e

-//              = p1 + p2 * 2^e
-//
-// The conversion of p1 into decimal form requires a series of divisions and
-// modulos by (a power of) 10. These operations are faster for 32-bit than for
-// 64-bit integers, so p1 should ideally fit into a 32-bit integer. This can be
-// achieved by choosing
-//
-//      -e >= 32   or   e <= -32 := gamma
-//
-// In order to convert the fractional part
-//
-//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...
-//
-// into decimal form, the fraction is repeatedly multiplied by 10 and the digits
-// d[-i] are extracted in order:
-//
-//      (10 * p2) div 2^-e = d[-1]
-//      (10 * p2) mod 2^-e = d[-2] / 10^1 + ...
-//
-// The multiplication by 10 must not overflow. It is sufficient to choose
-//
-//      10 * p2 < 16 * p2 = 2^4 * p2 <= 2^64.

-in @ref object_t)
-@tparam ArrayType type for JSON arrays (`std::vector` by default; will be used
-in @ref array_t)

-default)
-@tparam JSONSerializer the serializer to resolve internal calls to `to_json()`

-
-@requirement The class satisfies the following concept requirements:
-- Basic
- - [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible):
-   JSON values can be default constructed. The result will be a JSON null
-   value.
- - [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible):
-   A JSON value can be constructed from an rvalue argument.
- - [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible):
-   A JSON value can be copy-constructed from an lvalue expression.
- - [MoveAssignable](https://en.cppreference.com/w/cpp/named_req/MoveAssignable):
-   A JSON value van be assigned from an rvalue argument.
- - [CopyAssignable](https://en.cppreference.com/w/cpp/named_req/CopyAssignable):
-   A JSON value can be copy-assigned from an lvalue expression.
- - [Destructible](https://en.cppreference.com/w/cpp/named_req/Destructible):
-   JSON values can be destructed.
-- Layout
- - [StandardLayoutType](https://en.cppreference.com/w/cpp/named_req/StandardLayoutType):
-   JSON values have
-   [standard layout](https://en.cppreference.com/w/cpp/language/data_members#Standard_layout):
-   All non-static data members are private and standard layout types, the
-   class has no virtual functions or (virtual) base classes.
-- Library-wide
- - [EqualityComparable](https://en.cppreference.com/w/cpp/named_req/EqualityComparable):
-   JSON values can be compared with `==`, see @ref
-   operator==(const_reference,const_reference).
- - [LessThanComparable](https://en.cppreference.com/w/cpp/named_req/LessThanComparable):
-   JSON values can be compared with `<`, see @ref
-   operator<(const_reference,const_reference).
- - [Swappable](https://en.cppreference.com/w/cpp/named_req/Swappable):
-   Any JSON lvalue or rvalue of can be swapped with any lvalue or rvalue of
-   other compatible types, using unqualified function call @ref swap().
- - [NullablePointer](https://en.cppreference.com/w/cpp/named_req/NullablePointer):
-   JSON values can be compared against `std::nullptr_t` objects which are used
-   to model the `null` value.
-- Container
- - [Container](https://en.cppreference.com/w/cpp/named_req/Container):
-   JSON values can be used like STL containers and provide iterator access.
- - [ReversibleContainer](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer);
-   JSON values can be used like STL containers and provide reverse iterator
-   access.
-
-@invariant The member variables @a m_value and @a m_type have the following
-relationship:
-- If `m_type == value_t::object`, then `m_value.object != nullptr`.
-- If `m_type == value_t::array`, then `m_value.array != nullptr`.
-- If `m_type == value_t::string`, then `m_value.string != nullptr`.
-The invariants are checked by member function assert_invariant().

-    @brief a type for an object
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON objects as follows:
-    > An object is an unordered collection of zero or more name/value pairs,
-    > where a name is a string and a value is a string, number, boolean, null,
-    > object, or array.
-
-    To store objects in C++, a type is defined by the template parameters
-    described below.
-
-    @tparam ObjectType  the container to store objects (e.g., `std::map` or
-    `std::unordered_map`)
-    @tparam StringType the type of the keys or names (e.g., `std::string`).
-    The comparison function `std::less<StringType>` is used to order elements
-    inside the container.
-    @tparam AllocatorType the allocator to use for objects (e.g.,
-    `std::allocator`)
-
-    #### Default type
-
-    With the default values for @a ObjectType (`std::map`), @a StringType
-    (`std::string`), and @a AllocatorType (`std::allocator`), the default
-    value for @a object_t is:
-
-    @code {.cpp}
-    std::map<
-      std::string, // key_type
-      basic_json, // value_type
-      std::less<std::string>, // key_compare
-      std::allocator<std::pair<const std::string, basic_json>> // allocator_type
-    >
-    @endcode
-
-    #### Behavior
-
-    The choice of @a object_t influences the behavior of the JSON class. With
-    the default type, objects have the following behavior:
-
-    - When all names are unique, objects will be interoperable in the sense
-      that all software implementations receiving that object will agree on
-      the name-value mappings.
-    - When the names within an object are not unique, it is unspecified which
-      one of the values for a given key will be chosen. For instance,
-      `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
-      `{"key": 2}`.
-    - Internally, name/value pairs are stored in lexicographical order of the
-      names. Objects will also be serialized (see @ref dump) in this order.
-      For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
-      and serialized as `{"a": 2, "b": 1}`.
-    - When comparing objects, the order of the name/value pairs is irrelevant.
-      This makes objects interoperable in the sense that they will not be
-      affected by these differences. For instance, `{"b": 1, "a": 2}` and
-      `{"a": 2, "b": 1}` will be treated as equal.
-
-    #### Limits
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-    > An implementation may set limits on the maximum depth of nesting.
-
-    In this class, the object's limit of nesting is not explicitly constrained.
-    However, a maximum depth of nesting may be introduced by the compiler or
-    runtime environment. A theoretical limit can be queried by calling the
-    @ref max_size function of a JSON object.
-
-    #### Storage
-
-    Objects are stored as pointers in a @ref basic_json type. That is, for any
-    access to object values, a pointer of type `object_t*` must be
-    dereferenced.
-
-    @sa see @ref array_t -- type for an array value
-
-    @since version 1.0.0
-
-    @note The order name/value pairs are added to the object is *not*
-    preserved by the library. Therefore, iterating an object may return
-    name/value pairs in a different order than they were originally stored. In
-    fact, keys will be traversed in alphabetical order as `std::map` with
-    `std::less` is used by default. Please note this behavior conforms to [RFC
-    8259](https://tools.ietf.org/html/rfc8259), because any order implements the
-    specified "unordered" nature of JSON objects.

-
-    #### Encoding
-
-    Strings are stored in UTF-8 encoding. Therefore, functions like
-    `std::string::size()` or `std::string::length()` return the number of
-    bytes in the string rather than the number of characters or glyphs.
-
-    #### String comparison
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-    > Software implementations are typically required to test names of object
-    > members for equality. Implementations that transform the textual
-    > representation into sequences of Unicode code units and then perform the
-    > comparison numerically, code unit by code unit, are interoperable in the

-    > inequality of two strings. For example, implementations that compare
-    > strings with escaped characters unconverted may incorrectly find that
-    > `"a\\b"` and `"a\u005Cb"` are not equal.
-
-    This implementation is interoperable as it does compare strings code unit
-    by code unit.

-
-    This description includes both integer and floating-point numbers.
-    However, C++ allows more precise storage if it is known whether the number
-    is a signed integer, an unsigned integer or a floating-point number.
-    Therefore, three different types, @ref number_integer_t, @ref

-    @endcode
-
-    #### Default behavior
-
-    - The restrictions about leading zeros is not enforced in C++. Instead,
-      leading zeros in integer literals lead to an interpretation as octal
-      number. Internally, the value will be stored as decimal number. For
-      instance, the C++ integer literal `010` will be serialized to `8`.
-      During deserialization, leading zeros yield an error.
-    - Not-a-number (NaN) values will be serialized to `null`.
-
-    #### Limits

-    When the default type is used, the maximal integer number that can be
-    stored is `9223372036854775807` (INT64_MAX) and the minimal integer number
-    that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers
-    that are out of range will yield over/underflow when used in a
-    constructor. During deserialization, too large or small integer numbers
-    will be automatically be stored as @ref number_unsigned_t or @ref
-    number_float_t.
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) further states:
-    > Note that when such software is used, numbers that are integers and are

-    describes this type as:
-    > Bin format family stores an byte array in 2, 3, or 5 bytes of extra bytes
-    > in addition to the size of the byte array.
-
-    [BSON's specifications](http://bsonspec.org/spec.html) describe several
-    binary types; however, this type is intended to represent the generic binary
-    type which has the description:
-    > Generic binary subtype - This is the most commonly used binary subtype and
-    > should be the 'default' for drivers and tools.
-
-    None of these impose any limitations on the internal representation other
-    than the basic unit of storage be some type of array whose parts are
-    decomposable into bytes.
-
-    The default representation of this binary format is a
-    `std::vector<std::uint8_t>`, which is a very common way to represent a byte
-    array in modern C++.
-
-    #### Default type
-
-    The default values for @a BinaryType is `std::vector<std::uint8_t>`
-
-    #### Storage
-
-    Binary Arrays are stored as pointers in a @ref basic_json type. That is,
-    for any access to array values, a pointer of the type `binary_t*` must be
-    dereferenced.
-
-    #### Notes on subtypes
-
-    - CBOR
-       - Binary values are represented as byte strings. Subtypes are serialized
-         as tagged values.
-    - MessagePack
-       - If a subtype is given and the binary array contains exactly 1, 2, 4, 8,
-         or 16 elements, the fixext family (fixext1, fixext2, fixext4, fixext8)
-         is used. For other sizes, the ext family (ext8, ext16, ext32) is used.
-         The subtype is then added as singed 8-bit integer.
-       - If no subtype is given, the bin family (bin8, bin16, bin32) is used.
-    - BSON
-       - If a subtype is given, it is used and added as unsigned 8-bit integer.
-       - If no subtype is given, the generic binary subtype 0x00 is used.

-    @brief per-element parser callback type
-
-    With a parser callback function, the result of parsing a JSON text can be
-    influenced. When passed to @ref parse, it is called on certain events
-    (passed as @ref parse_event_t via parameter @a event) with a set recursion
-    depth @a depth and context JSON value @a parsed. The return value of the
-    callback function is a boolean indicating whether the element that emitted
-    the callback shall be kept or not.
-
-    We distinguish six scenarios (determined by the event type) in which the
-    callback function can be called. The following table describes the values
-    of the parameters @a depth, @a event, and @a parsed.
-
-    parameter @a event | description | parameter @a depth | parameter @a parsed
-    ------------------ | ----------- | ------------------ | -------------------
-    parse_event_t::object_start | the parser read `{` and started to process a JSON object | depth of the parent of the JSON object | a JSON value with type discarded
-    parse_event_t::key | the parser read a key of a value in an object | depth of the currently parsed JSON object | a JSON string containing the key
-    parse_event_t::object_end | the parser read `}` and finished processing a JSON object | depth of the parent of the JSON object | the parsed JSON object
-    parse_event_t::array_start | the parser read `[` and started to process a JSON array | depth of the parent of the JSON array | a JSON value with type discarded
-    parse_event_t::array_end | the parser read `]` and finished processing a JSON array | depth of the parent of the JSON array | the parsed JSON array
-    parse_event_t::value | the parser finished reading a JSON value | depth of the value | the parsed JSON value
-
-    @image html callback_events.png "Example when certain parse events are triggered"
-
-    Discarding a value (i.e., returning `false`) has different effects
-    depending on the context in which function was called:
-
-    - Discarded values in structured types are skipped. That is, the parser
-      will behave as if the discarded value was never read.
-    - In case a value outside a structured type is skipped, it is replaced
-      with `null`. This case happens if the top-level element is skipped.
-
-    @param[in] depth  the depth of the recursion during parsing
-
-    @param[in] event  an event of type parse_event_t indicating the context in
-    the callback function has been called
-
-    @param[in,out] parsed  the current intermediate parse result; note that
-    writing to this value has no effect for parse_event_t::key events
-
-    @return Whether the JSON value which called the function during parsing
-    should be kept (`true`) or not (`false`). In the latter case, it is either
-    skipped completely or replaced by an empty discarded object.

-    with `U = uncvref_t<CompatibleType>`, to be exact).
-
-    Template type @a CompatibleType includes, but is not limited to, the
-    following types:
-    - **arrays**: @ref array_t and all kinds of compatible containers such as
-      `std::vector`, `std::deque`, `std::list`, `std::forward_list`,
-      `std::array`, `std::valarray`, `std::set`, `std::unordered_set`,
-      `std::multiset`, and `std::unordered_multiset` with a `value_type` from
-      which a @ref basic_json value can be constructed.
-    - **objects**: @ref object_t and all kinds of compatible associative
-      containers such as `std::map`, `std::unordered_map`, `std::multimap`,
-      and `std::unordered_multimap` with a `key_type` compatible to
-      @ref string_t and a `value_type` from which a @ref basic_json value can
-      be constructed.
-    - **strings**: @ref string_t, string literals, and all compatible string
-      containers can be used.
-    - **numbers**: @ref number_integer_t, @ref number_unsigned_t,
-      @ref number_float_t, and all convertible number types such as `int`,
-      `size_t`, `int64_t`, `float` or `double` can be used.
-    - **boolean**: @ref boolean_t / `bool` can be used.
-    - **binary**: @ref binary_t / `std::vector<std::uint8_t>` may be used,
-      unfortunately because string literals cannot be distinguished from binary
-      character arrays by the C++ type system, all types compatible with `const
-      char*` will be directed to the string constructor instead.  This is both

-    - @a CompatibleType is not a @ref basic_json nested type (e.g.,

-    @brief create a container (array or object) from an initializer list
-
-    Creates a JSON value of type array or object from the passed initializer
-    list @a init. In case @a type_deduction is `true` (default), the type of
-    the JSON value to be created is deducted from the initializer list @a init
-    according to the following rules:
-
-    1. If the list is empty, an empty JSON object value `{}` is created.
-    2. If the list consists of pairs whose first element is a string, a JSON
-       object value is created where the first elements of the pairs are
-       treated as keys and the second elements are as values.
-    3. In all other cases, an array is created.
-
-    The rules aim to create the best fit between a C++ initializer list and
-    JSON values. The rationale is as follows:
-
-    1. The empty initializer list is written as `{}` which is exactly an empty
-       JSON object.
-    2. C++ has no way of describing mapped types other than to list a list of
-       pairs. As JSON requires that keys must be of type string, rule 2 is the
-       weakest constraint one can pose on initializer lists to interpret them
-       as an object.
-    3. In all other cases, the initializer list could not be interpreted as
-       JSON object type, so interpreting it as JSON array type is safe.
-
-    With the rules described above, the following JSON values cannot be
-    expressed by an initializer list:
-
-    - the empty array (`[]`): use @ref array(initializer_list_t)
-      with an empty initializer list in this case
-    - arrays whose elements satisfy rule 2: use @ref
-      array(initializer_list_t) with the same initializer list
-      in this case
-
-    @note When used without parentheses around an empty initializer list, @ref
-    basic_json() is called instead of this function, yielding the JSON null
-    value.
-
-    @param[in] init  initializer list with JSON values
-
-    @param[in] type_deduction internal parameter; when set to `true`, the type
-    of the JSON value is deducted from the initializer list @a init; when set
-    to `false`, the type provided via @a manual_type is forced. This mode is
-    used by the functions @ref array(initializer_list_t) and
-    @ref object(initializer_list_t).
-
-    @param[in] manual_type internal parameter; when @a type_deduction is set
-    to `false`, the created JSON value will use the provided type (only @ref
-    value_t::array and @ref value_t::object are valid); when @a type_deduction
-    is set to `true`, this parameter has no effect
-
-    @throw type_error.301 if @a type_deduction is `false`, @a manual_type is
-    `value_t::object`, but @a init contains an element which is not a pair
-    whose first element is a string. In this case, the constructor could not
-    create an object. If @a type_deduction would have be `true`, an array
-    would have been created. See @ref object(initializer_list_t)
-    for an example.
-
-    @complexity Linear in the size of the initializer list @a init.
-
-    @exceptionsafety Strong guarantee: if an exception is thrown, there are no

-    @brief serialization
-
-    Serialization function for JSON values. The function tries to mimic
-    Python's `json.dumps()` function, and currently supports its @a indent
-    and @a ensure_ascii parameters.
-
-    @param[in] indent If indent is nonnegative, then array elements and object
-    members will be pretty-printed with that indent level. An indent level of
-    `0` will only insert newlines. `-1` (the default) selects the most compact
-    representation.
-    @param[in] indent_char The character to use for indentation if @a indent is
-    greater than `0`. The default is ` ` (space).
-    @param[in] ensure_ascii If @a ensure_ascii is true, all non-ASCII characters
-    in the output are escaped with `\uXXXX` sequences, and the result consists
-    of ASCII characters only.
-    @param[in] error_handler  how to react on decoding errors; there are three
-    possible values: `strict` (throws and exception in case a decoding error
-    occurs; default), `replace` (replace invalid UTF-8 sequences with U+FFFD),
-    and `ignore` (ignore invalid UTF-8 sequences during serialization; all
-    bytes are copied to the output unchanged).
-
-    @return string containing the serialization of the JSON value
-
-    @throw type_error.316 if a string stored inside the JSON value is not
-                          UTF-8 encoded and @a error_handler is set to strict
-
-    @note Binary values are serialized as object containing two keys:
-      - "bytes": an array of bytes as integers
-      - "subtype": the subtype as integer or "null" if the binary has no subtype
-
-    @complexity Linear.
-
-    @exceptionsafety Strong guarantee: if an exception is thrown, there are no
-    changes in the JSON value.

-    @a indent_char\, and @a ensure_ascii parameters to the result of the

-    @brief comparison: equal
-
-    Compares two JSON values for equality according to the following rules:
-    - Two JSON values are equal if (1) they are from the same type and (2)
-      their stored values are the same according to their respective
-      `operator==`.
-    - Integer and floating-point numbers are automatically converted before
-      comparison. Note that two NaN values are always treated as unequal.
-    - Two JSON null values are equal.
-
-    @note Floating-point inside JSON values numbers are compared with
-    `json::number_float_t::operator==` which is `double::operator==` by
-    default. To compare floating-point while respecting an epsilon, an alternative
-    [comparison function](https://github.com/mariokonrad/marnav/blob/master/include/marnav/math/floatingpoint.hpp#L34-#L39)
-    could be used, for instance
-    @code {.cpp}
-    template<typename T, typename = typename std::enable_if<std::is_floating_point<T>::value, T>::type>
-    inline bool is_same(T a, T b, T epsilon = std::numeric_limits<T>::epsilon()) noexcept
-    {
-        return std::abs(a - b) <= epsilon;
-    }
-    @endcode
-    Or you can self-defined operator equal function like this:
-    @code {.cpp}
-    bool my_equal(const_reference lhs, const_reference rhs) {
-    const auto lhs_type lhs.type();
-    const auto rhs_type rhs.type();
-    if (lhs_type == rhs_type) {
-        switch(lhs_type)
-            // self_defined case
-            case value_t::number_float:
-                return std::abs(lhs - rhs) <= std::numeric_limits<float>::epsilon();
-            // other cases remain the same with the original
-            ...
-    }
-    ...
-    }
-    @endcode

-    @note The mapping is **complete** in the sense that any JSON value type
-          can be converted to a UBJSON value.
-
-    @note The following values can **not** be converted to a UBJSON value:
-          - strings with more than 9223372036854775807 bytes (theoretical)
-
-    @note The following markers are not used in the conversion:
-          - `Z`: no-op values are not created.
-          - `C`: single-byte strings are serialized with `S` markers.
-
-    @note Any UBJSON output created @ref to_ubjson can be successfully parsed
-          by @ref from_ubjson.
-
-    @note If NaN or Infinity are stored inside a JSON number, they are
-          serialized properly. This behavior differs from the @ref dump()
-          function which serializes NaN or Infinity to `null`.
-
-    @note The optimized formats for containers are supported: Parameter
-          @a use_size adds size information to the beginning of a container and
-          removes the closing marker. Parameter @a use_type further checks
-          whether all elements of a container have the same type and adds the
-          type marker to the beginning of the container. The @a use_type
-          parameter must only be used together with @a use_size = true. Note
-          that @a use_size = true alone may result in larger representations -
-          the benefit of this parameter is that the receiving side is
-          immediately informed on the number of elements of the container.
-
-    @note If the JSON data contains the binary type, the value stored is a list
-          of integers, as suggested by the UBJSON documentation.  In particular,
-          this means that serialization and the deserialization of a JSON
-          containing binary values into UBJSON and back will result in a
-          different JSON object.

-    @brief applies a JSON Merge Patch
-
-    The merge patch format is primarily intended for use with the HTTP PATCH
-    method as a means of describing a set of modifications to a target
-    resource's content. This function applies a merge patch to the current
-    JSON value.
-
-    The function implements the following algorithm from Section 2 of
-    [RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):
-
-    ```
-    define MergePatch(Target, Patch):
-      if Patch is an Object:
-        if Target is not an Object:
-          Target = {} // Ignore the contents and set it to an empty Object
-        for each Name/Value pair in Patch:
-          if Value is null:
-            if Name exists in Target:
-              remove the Name/Value pair from Target
-          else:
-            Target[Name] = MergePatch(Target[Name], Value)
-        return Target
-      else:
-        return Patch
-    ```
-
-    Thereby, `Target` is the current object; that is, the patch is applied to
-    the current value.
-
-    @param[in] apply_patch  the patch to apply
-
-    @complexity Linear in the lengths of @a patch.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-Installation Instructions
-*************************
-
-Copyright (C) 1994-1996, 1999-2002, 2004-2013 Free Software Foundation,
-Inc.
-
-   Copying and distribution of this file, with or without modification,
-are permitted in any medium without royalty provided the copyright
-notice and this notice are preserved.  This file is offered as-is,
-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.  Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the `make install' phase executed with root
-     privileges.
-
-  5. Optionally, type `make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior `make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  6. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  7. Often, you can also type `make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  8. Some packages, particularly those that use Automake, provide `make
-     distcheck', which can by used by developers to test that all other
-     targets like `make install' and `make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.  This
-is known as a "VPATH" build.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
-   The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
-   The first method involves providing an override variable for each
-affected directory.  For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'.  Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated.  The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the `DESTDIR' variable.  For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names.  The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of `make' will be.  For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved.  Use GNU `make'
-instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf limitation.  Until the limitation is lifted, you can use
-this workaround:
-
-     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names::
-     for more details, including other options available for fine-tuning
-     the installation locations.
-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-# Configuration subroutine to validate and canonicalize a configuration type.

-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.

-# This file is supposed to be the same for all GNU packages
-# and recognize all the CPU types, system types and aliases

-# configuration.
-
-# The goal of this file is to map all the various variations of a given

-#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:
-#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
-# It is wrong to echo any other type of specification.

-\`configure' configures Xdelta3 3.0.11 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-
-			       Xdelta 3
-
-   The goal of this library is to to implement both the (stand-alone)
-   data-compression and delta-compression aspects of VCDIFF encoding, and
-   to support a programming interface that works like Zlib
-   (http://www.gzip.org/zlib.html). See RFC3284: The VCDIFF Generic
-   Differencing and Compression Data Format.
-
-   VCDIFF is a unified encoding that combines data-compression and
-   delta-encoding ("differencing").
-
-   VCDIFF has a detailed byte-code instruction set with many features.
-   The instruction format supports an immediate size operand for small
-   COPYs and ADDs (e.g., under 18 bytes).  There are also instruction
-   "modes", which are used to compress COPY addresses by using two
-   address caches.  An instruction mode refers to slots in the NEAR
-   and SAME caches for recent addresses.  NEAR remembers the
-   previous 4 (by default) COPY addresses, and SAME catches
-   frequent re-uses of the same address using a 3-way (by default)
-   256-entry associative cache of [ADDR mod 256], the encoded byte.
-   A hit in the NEAR/SAME cache requires 0/1 ADDR bytes.
-
-   VCDIFF has a default instruction table, but an alternate
-   instruction tables may themselves be be delta-compressed and
-   included in the encoding header.  This allows even more freedom.
-   There are 9 instruction modes in the default code table, 4 near, 3
-   same, VCD_SELF (absolute encoding) and VCD_HERE (relative to the
-   current position).
-
-   ----------------------------------------------------------------------
-
-  			      Algorithms
-
-   Aside from the details of encoding and decoding, there are a bunch
-   of algorithms needed.
-
-   1. STRING-MATCH.  A two-level fingerprinting approach is used.  A
-   single loop computes the two checksums -- small and large -- at
-   successive offsets in the TARGET file.  The large checksum is more
-   accurate and is used to discover SOURCE matches, which are
-   potentially very long.  The small checksum is used to discover
-   copies within the TARGET.  Small matching, which is more expensive,
-   usually dominates the large STRING-MATCH costs in this code - the
-   more exhaustive the search, the better the results.  Either of the
-   two string-matching mechanisms may be disabled.
-
-   2. INSTRUCTION SELECTION.  The IOPT buffer here represents a queue
-   used to store overlapping copy instructions.  There are two possible
-   optimizations that go beyond a greedy search.  Both of these fall
-   into the category of "non-greedy matching" optimizations.
-
-   The first optimization stems from backward SOURCE-COPY matching.
-   When a new SOURCE-COPY instruction covers a previous instruction in
-   the target completely, it is erased from the queue.  Randal Burns
-   originally analyzed these algorithms and did a lot of related work
-   (\cite the 1.5-pass algorithm).
-
-   The second optimization comes by the encoding of common very-small
-   COPY and ADD instructions, for which there are special DOUBLE-code
-   instructions, which code two instructions in a single byte.
-
-   The cost of bad instruction-selection overhead is relatively high
-   for data-compression, relative to delta-compression, so this second
-   optimization is fairly important.  With "lazy" matching (the name
-   used in Zlib for a similar optimization), the string-match
-   algorithm searches after a match for potential overlapping copy
-   instructions.  In Xdelta and by default, VCDIFF, the minimum match
-   size is 4 bytes, whereas Zlib searches with a 3-byte minimum.  This
-   feature, combined with double instructions, provides a nice
-   challenge.  Search in this file for "black magic", a heuristic.
-
-   3. STREAM ALIGNMENT.  Stream alignment is needed to compress large
-   inputs in constant space.  See xd3_srcwin_move_point().
-
-   4. WINDOW SELECTION.  When the IOPT buffer flushes, in the first call
-   to xd3_iopt_finish_encoding containing any kind of copy instruction,
-   the parameters of the source window must be decided: the offset into
-   the source and the length of the window.  Since the IOPT buffer is
-   finite, the program may be forced to fix these values before knowing
-   the best offset/length.
-
-   5. SECONDARY COMPRESSION.  VCDIFF supports a secondary encoding to
-   be applied to the individual sections of the data format, which are
-   ADDRess, INSTruction, and DATA.  Several secondary compressor
-   variations are implemented here, although none is standardized yet.
-
-   One is an adaptive huffman algorithm -- the FGK algorithm (Faller,
-   Gallager, and Knuth, 1985).  This compressor is extremely slow.
-
-   The other is a simple static Huffman routine, which is the base
-   case of a semi-adaptive scheme published by D.J. Wheeler and first
-   widely used in bzip2 (by Julian Seward).  This is a very
-   interesting algorithm, originally published in nearly cryptic form
-   by D.J. Wheeler. !!!NOTE!!! Because these are not standardized,
-   secondary compression remains off by default.

-
-			    Other Features
-
-   1. USER CONVENIENCE
-
-   For user convenience, it is essential to recognize Gzip-compressed
-   files and automatically Gzip-decompress them prior to
-   delta-compression (or else no delta-compression will be achieved
-   unless the user manually decompresses the inputs).  The compressed
-   represention competes with Xdelta, and this must be hidden from the
-   command-line user interface.  The Xdelta-1.x encoding was simple, not
-   compressed itself, so Xdelta-1.x uses Zlib internally to compress the
-   representation.
-
-   This implementation supports external compression, which implements
-   the necessary fork() and pipe() mechanics.  There is a tricky step
-   involved to support automatic detection of a compressed input in a
-   non-seekable input.  First you read a bit of the input to detect
-   magic headers.  When a compressed format is recognized, exec() the
-   external compression program and create a second child process to
-   copy the original input stream. [Footnote: There is a difficulty
-   related to using Gzip externally. It is not possible to decompress
-   and recompress a Gzip file transparently.  If FILE.GZ had a
-   cryptographic signature, then, after: (1) Gzip-decompression, (2)
-   Xdelta-encoding, (3) Gzip-compression the signature could be
-   broken.  The only way to solve this problem is to guess at Gzip's
-   compression level or control it by other means.  I recommend that
-   specific implementations of any compression scheme store
-   information needed to exactly re-compress the input, that way
-   external compression is transparent - however, this won't happen
-   here until it has stabilized.]
-
-   2. APPLICATION-HEADER
-
-   This feature was introduced in RFC3284.  It allows any application
-   to include a header within the VCDIFF file format.  This allows
-   general inter-application data exchange with support for
-   application-specific extensions to communicate metadata.
-
-   3. VCDIFF CHECKSUM
-
-   An optional checksum value is included with each window, which can
-   be used to validate the final result.  This verifies the correct source
-   file was used for decompression as well as the obvious advantage:
-   checking the implementation (and underlying) correctness.
-
-   4. LIGHT WEIGHT
-
-   The code makes efforts to avoid copying data more than necessary.
-   The code delays many initialization tasks until the first use, it
-   optimizes for identical (perfectly matching) inputs.  It does not
-   compute any checksums until the first lookup misses.  Memory usage
-   is reduced.  String-matching is templatized (by slightly gross use
-   of CPP) to hard-code alternative compile-time defaults.  The code
-   has few outside dependencies.

-		     Reading the source: Overview
-
-   This file includes itself in several passes to macro-expand certain
-   sections with variable forms.  Just read ahead, there's only a
-   little confusion.  I know this sounds ugly, but hard-coding some of
-   the string-matching parameters results in a 10-15% increase in
-   string-match performance.  The only time this hurts is when you have
-   unbalanced #if/endifs.
-
-   A single compilation unit tames the Makefile.  In short, this is to
-   allow the above-described hack without an explodingMakefile.  The
-   single compilation unit includes the core library features,
-   configurable string-match templates, optional main() command-line
-   tool, misc optional features, and a regression test.  Features are
-   controled with CPP #defines, see Makefile.am.
-
-   The initial __XDELTA3_C_HEADER_PASS__ starts first, the _INLINE_ and
-   _TEMPLATE_ sections follow.  Easy stuff first, hard stuff last.
-
-   Optional features include:
-
-     xdelta3-main.h     The command-line interface, external compression
-                        support, POSIX-specific, info & VCDIFF-debug tools.
-     xdelta3-second.h   The common secondary compression routines.
-     xdelta3-decoder.h  All decoding routines.
-     xdelta3-djw.h      The semi-adaptive huffman secondary encoder.
-     xdelta3-fgk.h      The adaptive huffman secondary encoder.
-     xdelta3-test.h     The unit test covers major algorithms,
-                        encoding and decoding.  There are single-bit
-                        error decoding tests.  There are 32/64-bit file size
-                        boundary tests.  There are command-line tests.
-                        There are compression tests.  There are external
-                        compression tests.  There are string-matching tests.
-			There should be more tests...
-
-   Additional headers include:
-
-     xdelta3.h          The public header file.
-     xdelta3-cfgs.h     The default settings for default, built-in
-                        encoders.  These are hard-coded at
-                        compile-time.  There is also a single
-                        soft-coded string matcher for experimenting
-                        with arbitrary values.
-     xdelta3-list.h     A cyclic list template
-
-   Misc little debug utilities:
-
-     badcopy.c          Randomly modifies an input file based on two
-                        parameters: (1) the probability that a byte in
-                        the file is replaced with a pseudo-random value,
-                        and (2) the mean change size.  Changes are
-                        generated using an expoential distribution
-                        which approximates the expected error_prob
-			distribution.
-   --------------------------------------------------------------------
-
-   This file itself is unusually large.  I hope to defend this layout
-   with lots of comments.  Everything in this file is related to
-   encoding and decoding.  I like it all together - the template stuff
-   is just a hack. */

-/* The following code implements a parametrized description of the
- * code table given above for a few reasons.  It is not necessary for
- * implementing the standard, to support compression with variable
- * tables, so an implementation is only required to know the default
- * code table to begin decompression.  (If the encoder uses an
- * alternate table, the table is included in compressed form inside
- * the VCDIFF file.)
- *
- * Before adding variable-table support there were two functions which
- * were hard-coded to the default table above.
- * xd3_compute_default_table() would create the default table by
- * filling a 256-elt array of xd3_dinst values.  The corresponding
- * function, xd3_choose_instruction(), would choose an instruction
- * based on the hard-coded parameters of the default code table.
- *
- * Notes: The parametrized code table description here only generates
- * tables of a certain regularity similar to the default table by
- * allowing to vary the distribution of single- and
- * double-instructions and change the number of near and same copy
- * modes.  More exotic tables are only possible by extending this
- * code.
- *
- * For performance reasons, both the parametrized and non-parametrized
- * versions of xd3_choose_instruction remain.  The parametrized
- * version is only needed for testing multi-table decoding support.
- * If ever multi-table encoding is required, this can be optimized by
- * compiling static functions for each table.

-## ------ ##
-## Usage. ##
-## ------ ##
-
-# This file is a library for parsing options in your shell scripts along
-# with assorted other useful supporting features that you can make use
-# of too.
-#
-# For the simplest scripts you might need only:
-#
-#   #!/bin/sh
-#   . relative/path/to/funclib.sh
-#   . relative/path/to/options-parser
-#   scriptversion=1.0
-#   func_options ${1+"$@"}
-#   eval set dummy "$func_options_result"; shift
-#   ...rest of your script...
-#
-# In order for the '--version' option to work, you will need to have a
-# suitably formatted comment like the one at the top of this file
-# starting with '# Written by ' and ending with '# warranty; '.
-#
-# For '-h' and '--help' to work, you will also need a one line
-# description of your script's purpose in a comment directly above the
-# '# Written by ' line, like the one at the top of this file.
-#
-# The default options also support '--debug', which will turn on shell
-# execution tracing (see the comment above debug_cmd below for another
-# use), and '--verbose' and the func_verbose function to allow your script
-# to display verbose messages only when your user has specified

-   - Space and tab are interpreted as delimiters. They are not treated as
-     delimiters if they are surrounded by double quotes: "...".
-   - Unescaped double quotes are removed from the input. Their only effect is
-     that within double quotes, space and tab are treated like normal
-     characters.
-   - Backslashes not followed by double quotes are not special.
-   - But 2*n+1 backslashes followed by a double quote become
-     n backslashes followed by a double quote (n >= 0):
-       \" -> "

-# SYNOPSIS
-#
-#   AC_CHECK_ALIGNED_ACCESS_REQUIRED
-#
-# DESCRIPTION
-#
-#   While the x86 CPUs allow access to memory objects to be unaligned it
-#   happens that most of the modern designs require objects to be aligned -
-#   or they will fail with a buserror. That mode is quite known by
-#   big-endian machines (sparc, etc) however the alpha cpu is little-
-#   endian.
-#
-#   The following function will test for aligned access to be required and
-#   set a config.h define HAVE_ALIGNED_ACCESS_REQUIRED (name derived by
-#   standard usage). Structures loaded from a file (or mmapped to memory)
-#   should be accessed per-byte in that case to avoid segfault type errors.

-# serial 5 lt~obsolete.m4
-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-/* Each Huffman table consists of 256 "code length" (CLEN) codes,

- * djw_encode_basic plus a 4-bit value stating how many of the
- * djw_encode_extra codes are actually coded (the rest are presumed
- * zero, or unused CLEN codes).
- *
- * These values of these two arrays were arrived at by studying the
- * distribution of min and max clen over a collection of DATA, INST,
- * and ADDR inputs.  The goal is to specify the order of
- * djw_extra_codes that is most likely to minimize the number of extra

- * Results: 158896 sections were counted by compressing files (window
- * size 512K) listed with: `find / -type f ( -user jmacd -o -perm +444
- * )`
- *
- * The distribution of CLEN codes for each efficient invocation of the
- * secondary compressor (taking the best number of groups/sector size)
- * was recorded.  Then we look at the distribution of min and max clen
- * values, counting the number of times the value C_low is less than
- * the min and C_high is greater than the max.  Values >= C_high and
- * <= C_low will not have their lengths coded.  The results are sorted
- * and the least likely 15 are placed into the djw_encode_extra[]
- * array in order.  These values are used as the initial MTF ordering.

-
-			       Xdelta 3
-
-   The goal of this library is to to implement both the (stand-alone)
-   data-compression and delta-compression aspects of VCDIFF encoding, and
-   to support a programming interface that works like Zlib
-   (http://www.gzip.org/zlib.html). See RFC3284: The VCDIFF Generic
-   Differencing and Compression Data Format.
-
-   VCDIFF is a unified encoding that combines data-compression and
-   delta-encoding ("differencing").
-
-   VCDIFF has a detailed byte-code instruction set with many features.
-   The instruction format supports an immediate size operand for small
-   COPYs and ADDs (e.g., under 18 bytes).  There are also instruction
-   "modes", which are used to compress COPY addresses by using two
-   address caches.  An instruction mode refers to slots in the NEAR
-   and SAME caches for recent addresses.  NEAR remembers the
-   previous 4 (by default) COPY addresses, and SAME catches
-   frequent re-uses of the same address using a 3-way (by default)
-   256-entry associative cache of [ADDR mod 256], the encoded byte.
-   A hit in the NEAR/SAME cache requires 0/1 ADDR bytes.
-
-   VCDIFF has a default instruction table, but an alternate
-   instruction tables may themselves be be delta-compressed and
-   included in the encoding header.  This allows even more freedom.
-   There are 9 instruction modes in the default code table, 4 near, 3
-   same, VCD_SELF (absolute encoding) and VCD_HERE (relative to the
-   current position).
-
-   ----------------------------------------------------------------------
-
-  			      Algorithms
-
-   Aside from the details of encoding and decoding, there are a bunch
-   of algorithms needed.
-
-   1. STRING-MATCH.  A two-level fingerprinting approach is used.  A
-   single loop computes the two checksums -- small and large -- at
-   successive offsets in the TARGET file.  The large checksum is more
-   accurate and is used to discover SOURCE matches, which are
-   potentially very long.  The small checksum is used to discover
-   copies within the TARGET.  Small matching, which is more expensive,
-   usually dominates the large STRING-MATCH costs in this code - the
-   more exhaustive the search, the better the results.  Either of the
-   two string-matching mechanisms may be disabled.
-
-   2. INSTRUCTION SELECTION.  The IOPT buffer here represents a queue
-   used to store overlapping copy instructions.  There are two possible
-   optimizations that go beyond a greedy search.  Both of these fall
-   into the category of "non-greedy matching" optimizations.
-
-   The first optimization stems from backward SOURCE-COPY matching.
-   When a new SOURCE-COPY instruction covers a previous instruction in
-   the target completely, it is erased from the queue.  Randal Burns
-   originally analyzed these algorithms and did a lot of related work
-   (\cite the 1.5-pass algorithm).
-
-   The second optimization comes by the encoding of common very-small
-   COPY and ADD instructions, for which there are special DOUBLE-code
-   instructions, which code two instructions in a single byte.
-
-   The cost of bad instruction-selection overhead is relatively high
-   for data-compression, relative to delta-compression, so this second
-   optimization is fairly important.  With "lazy" matching (the name
-   used in Zlib for a similar optimization), the string-match
-   algorithm searches after a match for potential overlapping copy
-   instructions.  In Xdelta and by default, VCDIFF, the minimum match
-   size is 4 bytes, whereas Zlib searches with a 3-byte minimum.  This
-   feature, combined with double instructions, provides a nice
-   challenge.  Search in this file for "black magic", a heuristic.
-
-   3. STREAM ALIGNMENT.  Stream alignment is needed to compress large
-   inputs in constant space.  See xd3_srcwin_move_point().
-
-   4. WINDOW SELECTION.  When the IOPT buffer flushes, in the first call
-   to xd3_iopt_finish_encoding containing any kind of copy instruction,
-   the parameters of the source window must be decided: the offset into
-   the source and the length of the window.  Since the IOPT buffer is
-   finite, the program may be forced to fix these values before knowing
-   the best offset/length.
-
-   5. SECONDARY COMPRESSION.  VCDIFF supports a secondary encoding to
-   be applied to the individual sections of the data format, which are
-   ADDRess, INSTruction, and DATA.  Several secondary compressor
-   variations are implemented here, although none is standardized yet.
-
-   One is an adaptive huffman algorithm -- the FGK algorithm (Faller,
-   Gallager, and Knuth, 1985).  This compressor is extremely slow.
-
-   The other is a simple static Huffman routine, which is the base
-   case of a semi-adaptive scheme published by D.J. Wheeler and first
-   widely used in bzip2 (by Julian Seward).  This is a very
-   interesting algorithm, originally published in nearly cryptic form
-   by D.J. Wheeler. !!!NOTE!!! Because these are not standardized,
-   secondary compression remains off by default.

-
-			    Other Features
-
-   1. USER CONVENIENCE
-
-   For user convenience, it is essential to recognize Gzip-compressed
-   files and automatically Gzip-decompress them prior to
-   delta-compression (or else no delta-compression will be achieved
-   unless the user manually decompresses the inputs).  The compressed
-   represention competes with Xdelta, and this must be hidden from the
-   command-line user interface.  The Xdelta-1.x encoding was simple, not
-   compressed itself, so Xdelta-1.x uses Zlib internally to compress the
-   representation.
-
-   This implementation supports external compression, which implements
-   the necessary fork() and pipe() mechanics.  There is a tricky step
-   involved to support automatic detection of a compressed input in a
-   non-seekable input.  First you read a bit of the input to detect
-   magic headers.  When a compressed format is recognized, exec() the
-   external compression program and create a second child process to
-   copy the original input stream. [Footnote: There is a difficulty
-   related to using Gzip externally. It is not possible to decompress
-   and recompress a Gzip file transparently.  If FILE.GZ had a
-   cryptographic signature, then, after: (1) Gzip-decompression, (2)
-   Xdelta-encoding, (3) Gzip-compression the signature could be
-   broken.  The only way to solve this problem is to guess at Gzip's
-   compression level or control it by other means.  I recommend that
-   specific implementations of any compression scheme store
-   information needed to exactly re-compress the input, that way
-   external compression is transparent - however, this won't happen
-   here until it has stabilized.]
-
-   2. APPLICATION-HEADER
-
-   This feature was introduced in RFC3284.  It allows any application
-   to include a header within the VCDIFF file format.  This allows
-   general inter-application data exchange with support for
-   application-specific extensions to communicate metadata.
-
-   3. VCDIFF CHECKSUM
-
-   An optional checksum value is included with each window, which can
-   be used to validate the final result.  This verifies the correct source
-   file was used for decompression as well as the obvious advantage:
-   checking the implementation (and underlying) correctness.
-
-   4. LIGHT WEIGHT
-
-   The code makes efforts to avoid copying data more than necessary.
-   The code delays many initialization tasks until the first use, it
-   optimizes for identical (perfectly matching) inputs.  It does not
-   compute any checksums until the first lookup misses.  Memory usage
-   is reduced.  String-matching is templatized (by slightly gross use
-   of CPP) to hard-code alternative compile-time defaults.  The code
-   has few outside dependencies.

-		     Reading the source: Overview
-
-   This file includes itself in several passes to macro-expand certain
-   sections with variable forms.  Just read ahead, there's only a
-   little confusion.  I know this sounds ugly, but hard-coding some of
-   the string-matching parameters results in a 10-15% increase in
-   string-match performance.  The only time this hurts is when you have
-   unbalanced #if/endifs.
-
-   A single compilation unit tames the Makefile.  In short, this is to
-   allow the above-described hack without an explodingMakefile.  The
-   single compilation unit includes the core library features,
-   configurable string-match templates, optional main() command-line
-   tool, misc optional features, and a regression test.  Features are
-   controled with CPP #defines, see Makefile.am.
-
-   The initial __XDELTA3_C_HEADER_PASS__ starts first, the _INLINE_ and
-   _TEMPLATE_ sections follow.  Easy stuff first, hard stuff last.
-
-   Optional features include:
-
-     xdelta3-main.h     The command-line interface, external compression
-                        support, POSIX-specific, info & VCDIFF-debug tools.
-     xdelta3-second.h   The common secondary compression routines.
-     xdelta3-decoder.h  All decoding routines.
-     xdelta3-djw.h      The semi-adaptive huffman secondary encoder.
-     xdelta3-fgk.h      The adaptive huffman secondary encoder.
-     xdelta3-test.h     The unit test covers major algorithms,
-                        encoding and decoding.  There are single-bit
-                        error decoding tests.  There are 32/64-bit file size
-                        boundary tests.  There are command-line tests.
-                        There are compression tests.  There are external
-                        compression tests.  There are string-matching tests.
-			There should be more tests...
-
-   Additional headers include:
-
-     xdelta3.h          The public header file.
-     xdelta3-cfgs.h     The default settings for default, built-in
-                        encoders.  These are hard-coded at
-                        compile-time.  There is also a single
-                        soft-coded string matcher for experimenting
-                        with arbitrary values.
-     xdelta3-list.h     A cyclic list template
-
-   Misc little debug utilities:
-
-     badcopy.c          Randomly modifies an input file based on two
-                        parameters: (1) the probability that a byte in
-                        the file is replaced with a pseudo-random value,
-                        and (2) the mean change size.  Changes are
-                        generated using an expoential distribution
-                        which approximates the expected error_prob
-			distribution.
-   --------------------------------------------------------------------
-
-   This file itself is unusually large.  I hope to defend this layout
-   with lots of comments.  Everything in this file is related to
-   encoding and decoding.  I like it all together - the template stuff
-   is just a hack. */

-/* The following code implements a parametrized description of the
- * code table given above for a few reasons.  It is not necessary for
- * implementing the standard, to support compression with variable
- * tables, so an implementation is only required to know the default
- * code table to begin decompression.  (If the encoder uses an
- * alternate table, the table is included in compressed form inside
- * the VCDIFF file.)
- *
- * Before adding variable-table support there were two functions which
- * were hard-coded to the default table above.
- * xd3_compute_default_table() would create the default table by
- * filling a 256-elt array of xd3_dinst values.  The corresponding
- * function, xd3_choose_instruction(), would choose an instruction
- * based on the hard-coded parameters of the default code table.
- *
- * Notes: The parametrized code table description here only generates
- * tables of a certain regularity similar to the default table by
- * allowing to vary the distribution of single- and
- * double-instructions and change the number of near and same copy
- * modes.  More exotic tables are only possible by extending this
- * code.
- *
- * For performance reasons, both the parametrized and non-parametrized
- * versions of xd3_choose_instruction remain.  The parametrized
- * version is only needed for testing multi-table decoding support.
- * If ever multi-table encoding is required, this can be optimized by
- * compiling static functions for each table.
