%description
Simple DirectMedia Layer (SDL) is a cross-platform multimedia library
designed to provide fast access to the graphics frame buffer and audio device.

This code is a compatibility layer; it provides a binary-compatible API for
programs written against SDL 2.0, but it uses SDL 3.0 behind the scenes.

If you are writing new code, please target SDL 3.0 directly and do not use
this layer.

%description static
Simple DirectMedia Layer (SDL) is a cross-platform multimedia library
designed to provide fast access to the graphics frame buffer and audio device.

This code is a compatibility layer; it provides a static link library for
programs written against SDL 2.0, but it uses SDL 3.0 behind the scenes.
Note that applications that use this library will need to declare SDL2 as
a dependency manually, as the library is dlopen()'d to preserve APIs between
SDL-2.0 and SDL-3.0.

If you are writing new code, please target SDL 3.0 directly and do not use
this layer.
