+/**
+ * SECTION:gstinfo
+ * @short_description: Debugging and logging facilities
+ * @see_also: #gstreamer-gstconfig, #gstreamer-Gst for command line parameters
+ * and environment variables that affect the debugging output.
+ *
+ * GStreamer's debugging subsystem is an easy way to get information about what
+ * the application is doing. It is not meant for programming errors. Use GLib
+ * methods (g_warning and friends) for that.
+ *
+ * The debugging subsystem works only after GStreamer has been initialized
+ * - for example by calling gst_init().
+ *
+ * The debugging subsystem is used to log informational messages while the
+ * application runs. Each messages has some properties attached to it. Among
+ * these properties are the debugging category, the severity (called "level"
+ * here) and an optional #GObject it belongs to. Each of these messages is sent
+ * to all registered debugging handlers, which then handle the messages.
+ * GStreamer attaches a default handler on startup, which outputs requested
+ * messages to stderr.
+ *
+ * Messages are output by using shortcut macros like #GST_DEBUG,
+ * #GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log()
+ * with the right parameters.
+ * The only thing a developer will probably want to do is define his own
+ * categories. This is easily done with 3 lines. At the top of your code,
+ * declare
+ * the variables and set the default category.
+ * <informalexample>
+ * <programlisting>
+ * GST_DEBUG_CATEGORY_STATIC (my_category); // define category (statically)
+ * &hash;define GST_CAT_DEFAULT my_category // set as default
+ * </programlisting>
+ * </informalexample>
+ * After that you only need to initialize the category.
+ * <informalexample>
+ * <programlisting>
+ * GST_DEBUG_CATEGORY_INIT (my_category, "my category",
+ * 0, "This is my very own");
+ * </programlisting>
+ * </informalexample>
+ * Initialization must be done before the category is used first.
+ * Plugins do this
+ * in their plugin_init function, libraries and applications should do that
+ * during their initialization.
+ *
+ * The whole debugging subsystem can be disabled at build time with passing the
+ * --disable-gst-debug switch to configure. If this is done, every function,
+ * macro and even structs described in this file evaluate to default values or
+ * nothing at all.
+ * So don't take addresses of these functions or use other tricks.
+ * If you must do that for some reason, there is still an option.
+ * If the debugging
+ * subsystem was compiled out, #GST_DISABLE_GST_DEBUG is defined in
+ * <gst/gst.h>,
+ * so you can check that before doing your trick.
+ * Disabling the debugging subsystem will give you a slight (read: unnoticeable)
+ * speed increase and will reduce the size of your compiled code. The GStreamer
+ * library itself becomes around 10% smaller.
+ *
+ * Please note that there are naming conventions for the names of debugging
+ * categories. These are explained at GST_DEBUG_CATEGORY_INIT().
