+ * - 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
