* Since Wiiuse is a library, wiiuse.h is a duplicate

|
||
|
|
*
|
||
|
|
* The code that would normally go in that file, but
|

|
|
* which is not needed by third party developers,
|
||
|
|
* is put here.
|
||
|
|
*
|
||
|
|
* So wiiuse_internal.h is included by other files
|
||
|
|
* internally, wiiuse.h is included only here.
