- * #GMountOperation provides a mechanism for authenticating mountable
- * operations, such as loop mounting files, hard drive partitions or
- * server locations.
+ * #GMountOperation provides a mechanism for interacting with the user.
+ * It can be used for authenticating mountable operations, such as loop
+ * mounting files, hard drive partitions or server locations. It can
+ * also be used to ask the user questions or show a list of applications
+ * preventing unmount or eject operations from completing.
*
- * Mountable GIO backends should implement #GMountOperation if they
- * require any priviledges or authentication for their volumes to be
- * mounted (e.g. a hard disk partition or an encrypted filesystem), or
- * if they are implementing a remote server protocol which requires user
- * credentials such as FTP or WebDAV.

+ * Note that #GMountOperation is used for more than just #GMount
+ * objects – for example it is also used in g_drive_start() and
+ * g_drive_stop().
+ *
+ * Users should instantiate a subclass of this that implements all the
+ * various callbacks to show the required dialogs, such as
+ * #GtkMountOperation. If no user interaction is desired (for example
+ * when automounting filesystems at login time), usually %NULL can be
+ * passed, see each method taking a #GMountOperation for details.
