* 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
