+ * SECTION:gvolume
+ * @short_description: mounted volume management
+ * 
+ * Class for managing mounted volumes.
+ * 
+ * Unmounting volumes is an asynchronous operation. For more information about
+ * asynchronous operations, see #GAsyncReady and #GSimpleAsyncReady. To unmount a volume, 
+ * first call g_volume_unmount() with (at least) the volume and a #GAsyncReadyCallback.
+ * The callback will be fired when the operation has resolved (either with success or failure), 
+ * and a #GAsyncReady structure will be passed to the callback. 
+ * That callback should then call g_volume_unmount_finish() with
+ * the volume and the #GAsyncReady data to see if the operation was completed successfully.
+ * If an @error is present when g_volume_unmount_finish() is called, then it will
+ * be filled with any error information.
+ * 
+ * Ejecting volumes is also an asynchronous operation. 
+ * To eject a volume, call g_volume_eject() with (at least) the volume to eject 
+ * and a #GAsyncReadyCallback. The callback will be fired when the eject operation
+ * has resolved (either with success or failure), and a #GAsyncReady structure will
+ * be passed to the callback. That callback should then call g_volume_eject_finish()
+ * with the volume and the #GAsyncReady data to determine if the operation was completed
+ * successfully. If an @error is present when g_volume_eject_finish() is called, then
+ * it will be filled with any error information.
