    (description
     "Florence is an extensible scalable virtual keyboard for X11.
It is useful for people who can't use a real hardware keyboard (for
example for people with disabilities), but you must be able to use
a pointing device (as a mouse, a trackball, a touchscreen or opengazer).

Florence stays out of your way when you don't need it: it appears on the
screen only when you need it.  A timer-based auto-click input method is
available to help to click.")
