/* At least since Windows 2000 it's possible to add FolderShortcut objects
* by creating some registry entries. Those objects, which refer to some
* point in the filesystem, can be registered in the shell namespace like other
* shell namespace extensions. Icons, names and filesystem location can be
* configured. This is documented at http://www.virtualplastic.net/html/ui_shell.html
* You can also google for a tool called "ShellObjectEditor" by "Tropical
* Technologies". This mechanism would be cool for wine, since we could
* map Gnome's virtual devices to FolderShortcuts and have them appear in the
* file dialogs. These unit tests are meant to document how this mechanism
* works on windows.
*
* Search MSDN for "Creating Shell Extensions with Shell Instance Objects" for
* more documentation.*/
