  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.
  31  *
  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.
  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.
