// 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 and XFCE 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.
