    (description
     "GStreamer is a library for constructing graphs of media-handling
components.  The applications it supports range from simple Ogg/Vorbis
playback, audio/video streaming to complex audio mixing and video
non-linear editing.

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.")
