+/**
+ * SECTION:gst
+ * @short_description: Media library supporting arbitrary formats and filter
+ *                     graphs.
+ * @see_also: Check out both <ulink url="http://www.cse.ogi.edu/sysl/">OGI's
+ *            pipeline</ulink> and Microsoft's DirectShow for some background.
+ *
+ * GStreamer is a framework for constructing graphs of various filters
+ * (termed elements here) that will handle streaming media.  Any discreet
+ * (packetizable) media type is supported, with provisions for automatically
+ * determining source type.  Formatting/framing information is provided with
+ * a powerful negotiation framework.  Plugins are heavily used to provide for
+ * all elements, allowing one to construct plugins outside of the GST
+ * library, even released binary-only if license require (please don't).
+ *
+ * GStreamer borrows heavily from both the <ulink
+ * url="http://www.cse.ogi.edu/sysl/">OGI media pipeline</ulink> and
+ * Microsoft's DirectShow, hopefully taking the best of both and leaving the
+ * cruft behind. Its interface is slowly getting stable.
+ *
+ * The <application>GStreamer</application> library should be initialized with
+ * gst_init() before it can be used. You should pass pointers to the main argc
+ * and argv variables so that GStreamer can process its own command line
+ * options, as shown in the following example.
+ *
+ * <example>
+ * <title>Initializing the gstreamer library</title>
+ * <programlisting language="c">
+ * int
+ * main (int argc, char *argv[])
+ * {
+ *   // initialize the GStreamer library
+ *   gst_init (&amp;argc, &amp;argv);
+ *   ...
+ * }
+ * </programlisting>
+ * </example>
+ *
+ * It's allowed to pass two NULL pointers to gst_init() in case you don't want
+ * to pass the command line args to GStreamer.
+ *
+ * You can also use GOption to initialize your own parameters as shown in
+ * the next code fragment:
+ * <example>
+ * <title>Initializing own parameters when initializing gstreamer</title>
+ * <programlisting>
+ * static gboolean stats = FALSE;
+ * ...
+ * int
+ * main (int argc, char *argv[])
+ * {
+ *  GOptionEntry options[] = {
+ *   {"tags", 't', 0, G_OPTION_ARG_NONE, &amp;tags,
+ *       N_("Output tags (also known as metadata)"), NULL},
+ *   {NULL}
+ *  };
+ *  // must initialise the threading system before using any other GLib funtion
+ *  if (!g_thread_supported ())
+ *    g_thread_init (NULL);
+ *  ctx = g_option_context_new ("[ADDITIONAL ARGUMENTS]");
+ *  g_option_context_add_main_entries (ctx, options, GETTEXT_PACKAGE);
+ *  g_option_context_add_group (ctx, gst_init_get_option_group ());
+ *  if (!g_option_context_parse (ctx, &amp;argc, &amp;argv, &amp;err)) {
+ *    g_print ("Error initializing: &percnt;s\n", GST_STR_NULL (err->message));
+ *    exit (1);
+ *  }
+ *  g_option_context_free (ctx);
+ * ...
+ * }
+ * </programlisting>
+ * </example>
+ *
+ * Use gst_version() to query the library version at runtime or use the
+ * GST_VERSION_* macros to find the version at compile time. Optionally
+ * gst_version_string() returns a printable string.
+ *
+ * The gst_deinit() call is used to clean up all internal resources used
+ * by <application>GStreamer</application>. It is mostly used in unit tests 
+ * to check for leaks.
+ *
