25 * This program is used to replicate the Windows desktop and start menu
26 * into the native desktop's copies. Desktop entries are merged directly
27 * into the native desktop. The Windows Start Menu corresponds to a Wine
28 * entry within the native "start" menu and replicates the whole tree
29 * structure of the Windows Start Menu. Currently it does not differentiate
30 * between the user's desktop/start menu and the "All Users" copies.
32 * This program will read a Windows shortcut file using the IShellLink
33 * interface, then invoke wineshelllink with the appropriate arguments
34 * to create a KDE/Gnome menu entry for the shortcut.
36 * winemenubuilder [ -w ] <shortcut.lnk>
38 * If the -w parameter is passed, and the shortcut cannot be created,
39 * this program will wait for the parent process to finish and then try
40 * again. This covers the case when a ShortCut is created before the
41 * executable containing its icon.
44 * Handle data lnk files. There is no icon in the file; the icon is in
45 * the handler for the file type (or pointed to by the lnk file). Also it
46 * might be better to use a native handler (e.g. a native acroread for pdf
48 * Differentiate between the user's entries and the "All Users" entries.
49 * If it is possible to add the desktop files to the native system's
50 * shared location for an "All Users" entry then do so. As a suggestion the
51 * shared menu Wine base could be writable to the wine group, or a wineadm
