   1 """To create a panel applet for ROX-Filer, you should add a file called
   2 AppletRun to your application. This is run when your applet it dragged onto
   3 a panel. It works like the usual AppRun, except that it is passed the XID of
   4 the GtkSocket widget that ROX-Filer creates for you on the panel.
   5
   6 A sample AppletRun might look like this:
