There's a new Quixote snapshot available at:

  http://www.mems-exchange.org/software/files/quixote/Quixote-20031008.tar.gz

Those of you on the quixote-checkins list might have noticed the
"next generation form framework" checkin.  That's the new toy in
this snapshot and we would appreciate feedback on it.  We hope to
one day replace the existing 'form' package with the new one
(currently called form2).

We think the new framework is considerably less magical than the old
one and more flexible to boot.  The major change is that, if the
form is submitted, widgets parse themselves when initialized.  That
simplifies a lot of other things.

The documentation is not finished but I attached a small example
form.
