+    \class UiGuiIniFileParser
+    \ingroup grp_Settings
+    \brief UiGuiIniFileParser is a simple ini file format parser.
+
+    These ini files need to have key-value pairs in the style
+    "keyname=keyvalue". Groups can be defined by writing the groupname
+    in the style [groupname] before some key-value pairs.
+
+    The reason why I use my own class instead of QSettings is mainly, that
+    QSettings always internally sorts the groups alphabetically and also
+    rewrites a settings file sorted. Very annoying for me.
