 * @Short_description: Remote repository
 * @Title: FlatpakRemote
 *
 * A #FlatpakRemote object provides information about a remote
 * repository (or short: remote) that has been configured.
 *
 * At its most basic level, a remote has a name and the URL for
 * the repository. In addition, they provide some additional
 * information that can be useful when presenting repositories
 * in a UI, such as a title, a priority or a "don't enumerate"
 * flags.
 *
 * To obtain FlatpakRemote objects for the configured remotes
 * on a system, use flatpak_installation_list_remotes() or
 * flatpak_installation_get_remote_by_name().
