 * Provides static methods to make use of desktop files provided by

 * registerServiceByDesktopEntryName creates a KMoreToolsService instance
 * from a given desktopEntryName.
 *
 * registerServicesByGroupingNames takes a list of a set of predefined
 * grouping names and returns a list KMoreToolsService instances. Remember,

 * installed on the current maschine.
 *
 * The groupings defined here are used for the KMoreToolsMenuFactory.

 * this class to KMoreToolsMenuFactory because grouping names and special
 * handling are too much coupled anyway.)
