+ Loading assets
+================================================================================
+
+Any files you put in the "assets" directory of your android-project directory
+will get bundled into the application package and you can load them using the
+standard functions in SDL_rwops.h.
+
+There are also a few Android specific functions that allow you to get other
+useful paths for saving and loading data:
+SDL_AndroidGetInternalStoragePath()
+SDL_AndroidGetExternalStorageState()
+SDL_AndroidGetExternalStoragePath()
+
+See SDL_system.h for more details on these functions.
