Binary package “fookb-plainx” in ubuntu precise
An Xkb state indicator -- plain X version.
WindowMaker docked Xkb state indicator. Fookb can switch xkb groups
and display a pixmap corresponding to the selected group. It also can
execute a specified command upon the switch (for example, play sound).
This is the plain X-compiled version. It can't do docking, and uses
only X resources for configuration.
