 SDL is a library that allows programs portable low level access to
 a video framebuffer, audio output, mouse, and keyboard.
 .
 This is just a dummy package. You also need one of the seven versions of
 the library that this package depends on.

 (Note: Updates from SDL CVS after the version release date are occasionally
 factored into these packages).
