/**
* SECTION:gstregistry
+ * @title: GstRegistry
* @short_description: Abstract base class for management of #GstPlugin objects
* @see_also: #GstPlugin, #GstPluginFeature
*
*
* On startup, plugins are searched for in the plugin search path. The following
* locations are checked in this order:
- * <itemizedlist>
- * <listitem>
- * <para>location from --gst-plugin-path commandline option.</para>
- * </listitem>
- * <listitem>
- * <para>the GST_PLUGIN_PATH environment variable.</para>
- * </listitem>
- * <listitem>
- * <para>the GST_PLUGIN_SYSTEM_PATH environment variable.</para>
- * </listitem>
- * <listitem>
- * <para>default locations (if GST_PLUGIN_SYSTEM_PATH is not set). Those
- * default locations are:
- * <filename>~/.gstreamer-$GST_API_VERSION/plugins/</filename>
- * and <filename>$prefix/libs/gstreamer-$GST_API_VERSION/</filename>.
- * </para>
- * </listitem>
- * </itemizedlist>
+ *
+ * * location from --gst-plugin-path commandline option.
+ * * the GST_PLUGIN_PATH environment variable.
+ * * the GST_PLUGIN_SYSTEM_PATH environment variable.
+ * * default locations (if GST_PLUGIN_SYSTEM_PATH is not set).
+ * Those default locations are:
+ * `$XDG_DATA_HOME/gstreamer-$GST_API_VERSION/plugins/`
+ * and `$prefix/libs/gstreamer-$GST_API_VERSION/`.
+ * [$XDG_DATA_HOME](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) defaults to
+ * `$HOME/.local/share`.
+ *
* The registry cache file is loaded from
- * <filename>~/.gstreamer-$GST_API_VERSION/registry-$ARCH.bin</filename> or the
- * file listed in the GST_REGISTRY env var. One reason to change the registry
- * location is for testing.
+ * `$XDG_CACHE_HOME/gstreamer-$GST_API_VERSION/registry-$ARCH.bin`
+ * (where $XDG_CACHE_HOME defaults to `$HOME/.cache`) or the file listed in the `GST_REGISTRY`
+ * env var. One reason to change the registry location is for testing.
*
* For each plugin that is found in the plugin search path, there could be 3
* possibilities for cached information:
- * <itemizedlist>
- * <listitem>
- * <para>the cache may not contain information about a given file.</para>
- * </listitem>
- * <listitem>
- * <para>the cache may have stale information.</para>
- * </listitem>
- * <listitem>
- * <para>the cache may have current information.</para>
- * </listitem>
- * </itemizedlist>
+ *
+ * * the cache may not contain information about a given file.
+ * * the cache may have stale information.
+ * * the cache may have current information.
*
* In the first two cases, the plugin is loaded and the cache updated. In
* addition to these cases, the cache may have entries for plugins that are not
* checked to make sure the information is minimally valid. If not, the entry is
* simply dropped.
*
- * <emphasis role="bold">Implementation notes:</emphasis>
+ * ## Implementation notes:
*
* The "cache" and "registry" are different concepts and can represent
* different sets of plugins. For various reasons, at init time, the cache is
* stored in the default registry, and plugins not relevant to the current
* process are marked with the %GST_PLUGIN_FLAG_CACHED bit. These plugins are
* removed at the end of initialization.
