-      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) 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.
