+        On Windows and Mac OS X, the tray is always available and this function
+        simply returns true.
+
+        On Unix, X11 environment may or may not provide the tray, depending on
+        user's desktop environment. Most modern desktops support the tray via
+        the System Tray Protocol by freedesktop.org
+        (http://freedesktop.org/wiki/Specifications/systemtray-spec).
+
+        @note Tray availability may change during application's lifetime
+              under X11 and so applications shouldn't cache the result.
+
+        @note wxTaskBarIcon supports older GNOME 1.2 and KDE 1/2 methods of
+              adding icons to tray, but they are unreliable and this method
