  24  *  This program will read a Windows shortcut file using the IShellLink
  25  * interface, then invoke wineshelllink with the appropriate arguments
  26  * to create a KDE/Gnome menu entry for the shortcut.
  27  *
  28  *  winemenubuilder [ -r ] <shortcut.lnk>
  29  *
  30  *  If the -r parameter is passed, and the shortcut cannot be created,
  31  * this program will add RunOnce entry to invoke itself at the next
  32  * reboot.  This covers the case when a ShortCut is created before the
  33  * executable containing its icon.
