KKBSwitch is a keyboard layout indicator for KDE 2 or 3.  It is useful when you
have configured the XKeyboard extension of your X Server to have more than one
keyboard group (layout), for example US/ASCII and Russian.  KKBSwitch displays
an icon in the system tray that indicates which layout is currently active.
Note that KKBSwitch does not help you configure XKeyboard, it merely serves as
the indicator of the current layout.  You still have to configure XKeyboard by
editing the XF86Config file.
