+MIDI, Ogg Vorbis, and MP3.

+This package supports two MIDI backends, selectable at runtime. To use the
+newer @code{fluidsynth} library, install a soundfont such as @code{fluid-3}
+and specify it using the @code{SDL_SOUNDFONTS} environment variable. For the
+legacy @code{timidity} backend, install a patch set such as @code{freepats}
+and set the path to the configuration file with @code{TIMIDITY_CFG}.")
