  22  * Howto debug:
  23  *    start "kinfocenter --nofork" in a debugger.
  24  *
  25  * If you want to test with command line arguments you need
  26  * -after you have started kinfocenter in the debugger-
  27  * open another shell and run kinfocenter with the desired
  28  * command line arguments.
  29  *
  30  * The command line arguments will be passed to the version of
  31  * kinfocenter in the debugger via DCOP and will cause a call
  32  * to newInstance().
