I'd really recommend using the Savannah CVS.  Anything else will
be very old and buggy.

Some of that is fixed in CVS.  Some is not (particularly in
CROSSTABS, which needs to be rewritten anyway).

You're not the first to suggest a GUI.  A couple of people have
come up with prototypes but I don't know if any of them did
anything--I think at least one was just pretty sets of menus that
weren't "hooked up" to actions.

You're welcome to build a GUI if you're interested.  At one point
I had very specific ideas on how a GUI should be done but I'm
willing to settle for anything now.

If you build a GUI, I hope you can coordinate with anyone else
who is interested.

I know that's the way older versions of SPSS and SPSS/PC+
worked.  I haven't played with any recent versions of SPSS though
so I don't know if it still works that way.

That would be fine.  It's actually a nice way to go in some
respects because it means you can easily record an analysis and
then replay it later on different data.
