-As you can see, {fmt} has 60% less overhead in terms of resulting binary
-code size compared to iostreams and comes pretty close to `printf`.
-Boost Format and Folly Format have the largest overheads.
-
-`printf+string` is the same as `printf` but with an extra `<string>`
-include to measure the overhead of the latter.
+{fmt} is fast to compile and is comparable to `printf` in terms of per-call
+binary size (within a rounding error on this system).
