+components.  The applications it supports range from simple Ogg/Vorbis
+playback, audio/video streaming to complex audio (mixing) and video
+(non-linear editing) processing.
+
+Applications can take advantage of advances in codec and filter technology
+transparently.  Developers can add new codecs and filters by writing a
+simple plugin with a clean, generic interface.
+
+This package provides the core library and elements.")
