- * SECTION:gis-prefs
- * @short_description: Persistent preference handing
- *
- * #GisPrefs is used to store and access preferences in libgis. It is mostly a
- * wrapper around a #GKeyFile. Preferences can be stored for the application
- * using libgis, but may also be stored by libgis itself. An example of this are
- * whether libgis is in online or offline mode. Many #GisPlugin<!-- -->s also
- * store preferences.
- *
- * There are two variants of preference functions. The normal variant takes
- * group and a key separated by a "/" as they key to the preference. The "_v"
- * variant takes the group and the key as separate parameters.
