+/// Though it's possible to use SDL_mixer without initializing it,
+/// library provides initialization/deinitialization functions to
+/// be able to preload libraries for specific file format support
+/// (png, jpeg or tiff) beforehand. In SDL2pp, this is handled by
+/// this class.
+///
+/// Usage example:
+/// \code
+/// int main() {
+///     SDL2pp::SDL sdl(SDL_INIT_VIDEO);
+///     SDL2pp::SDLMixer mixer(IMG_INIT_PNG);
+///
+///     // use SDL_mixer functions
+///     SDL2pp::Texture t("/path/to/file.png");
+///
+///     // SDL_mixer library is automatically deinitialized before exit
+///     return 0;
+/// }
+/// \endcode
