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