 *  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 create a KDE/GNOME menu entry for the shortcut.
 *
 *  winemenubuilder [ -w ] <shortcut.lnk>
 *
 *  If the -w parameter is passed, and the shortcut cannot be created,
 * this program will wait for the parent process to finish and then try
 * again. 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.
 *  Clean up fd.o menu icons and .directory files when the menu is deleted
 * in Windows.
 *  Associate applications under HKCR\Applications to open any MIME type
 * (by associating with application/octet-stream, or how?).
 *  Clean up fd.o MIME types when they are deleted in Windows, their icons
 * too. Very hard - once we associate them with fd.o, we can't tell whether
 * they are ours or not, and the extension <-> MIME type mapping isn't
 * one-to-one either.
 *  Wine's HKCR is broken - it doesn't merge HKCU\Software\Classes, so apps
 * that write associations there won't associate (#17019).
