The future SCIX toolkit does not exist yet. The only things available at this
time are various kinds of buttons (ordinary, text-, pixmap- and toggle- ditto).
They are all defined in the file buttons.sc and are subclassed from a general
finite state machine which is defined and described in dfsm.sc.

This is where we will put our future effort, so the toolkit will certainly
change. What is included here is only an example of our current thoughts, or
rather our thoughts yesterday. This button implementation is not the last word
in any way.

We apologize for the lack of documentation.
