/**
* SECTION:gmountoperation
* @short_description: Authentication methods for mountable locations
*
* #GMountOperation provides a mechanism for authenticating mountable
* operations, such as loop mounting files, hard drive partitions or
* server locations.
*
* Mountable GIO backends should implement #GMountOperation if they
* require any privileges 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.
