 // NB: This implementation does *not* work with every X11 window manager.
-//     Currently only GNOME 1.2 and KDE 1,2,3 methods are implemented.
-//
-//     FIXME: implement:
-//               - GNOME 2 support (see www.freedesktop.org for specification;
-//                 KDE 3 uses this method as well, even though legacy KDE
-//                 method we implement works as well)
-//               - IceWM support (?)
+//     Currently only GNOME 1.2 and KDE 1,2,3 methods are implemented here.
+//     Freedesktop.org's System Tray specification is implemented in
+//     src/gtk/taskbar.cpp and used from here under wxGTK.
 //
 //     Thanks to Ian Campbell, author of XMMS Status Docklet, for publishing
 //     KDE and GNOME 1.2 methods.
