*
* This program is used to replicate the Windows desktop and start menu
* into the native desktop's copies. Desktop entries are merged directly
* into the native desktop. The Windows Start Menu corresponds to a Wine
* entry within the native "start" menu and replicates the whole tree
* structure of the Windows Start Menu. Currently it does not differentiate
* between the user's desktop/start menu and the "All Users" copies.
*
* 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 a RunOnce entry to invoke itself at the next
* reboot. This covers the case when a ShortCut is created before the
* executable containing its icon.
*
* TODO
* Handle data lnk files. There is no icon in the file; the icon is in
* the handler for the file type (or pointed to by the lnk file). Also it
* might be better to use a native handler (e.g. a native acroread for pdf
* files).
* Differentiate between the user's entries and the "All Users" entries.
* If it is possible to add the desktop files to the native system's
* shared location for an "All Users" entry then do so. As a suggestion the
* shared menu Wine base could be writable to the wine group, or a wineadm
* group.
