+ * Implementation of simple checking mechanism. Rules are defined in
+ * the form of an URI. Available syntax is:
+ *	- exec:/<execname>	->	check for an executable in
+ *					$PATH variable.
+ *	- config:/path/to/file	->      check for the existence of a file
+ *					or directory in KDE or standard
+ *					UNIX config locations
+ *	- file:/path/to/file
+ *	- dir:/path/to/dir	->	simply check the existence of the
+ *					a file or directory
+ *	- service:/serv 	->	try to connect to a port on the
+ *					specified host (usually localhost)
+ *					"serv" can be a port value or service name
+ *
+ * TO BE IMPLEMENTED:
+ *	- run:/<execname>	->	check for a running executable
