  26  *  This program is used to replicate the Windows desktop and start menu
  27  * into the native desktop's copies.  Desktop entries are merged directly
  28  * into the native desktop.  The Windows Start Menu corresponds to a Wine
  29  * entry within the native "start" menu and replicates the whole tree
  30  * structure of the Windows Start Menu.  Currently it does not differentiate
  31  * between the user's desktop/start menu and the "All Users" copies.
  32  *
  33  *  This program will read a Windows shortcut file using the IShellLink
  34  * interface, then create a KDE/Gnome menu entry for the shortcut.
  35  *
  36  *  winemenubuilder [ -w ] <shortcut.lnk>
  37  *
  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.
  42  *
  43  * TODO
  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
  47  * files).
  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
  52  * group.
  53  *  Clean up fd.o menu icons and .directory files when the menu is deleted
  54  * in Windows.
  55  *  Generate icons for file open handlers to go into the "Open with..."
  56  * list. What does Windows use, the default icon for the .EXE file? It's
  57  * not in the registry.
  58  *  Associate applications under HKCR\Applications to open any MIME type
  59  * (by associating with application/octet-stream, or how?).
  60  *  Clean up fd.o MIME types when they are deleted in Windows, their icons
  61  * too. Very hard - once we associate them with fd.o, we can't tell whether
  62  * they are ours or not, and the extension <-> MIME type mapping isn't
  63  * one-to-one either.
  64  *  Wine's HKCR is broken - it doesn't merge HKCU\Software\Classes, so apps
  65  * that write associations there won't associate (#17019).
