  On the concept of wizards, dialog boxes, what have you, Paul
Kinnucan has a small wizard library, and a dialog box library which he
wrote for dealing with the complexities of the JDE, and all the
options it has.  (I added Paul the CC list above so he can correct me
if I make an error.)

  The dialog box stuff (which I am guessing would interest you most,
since his wizards are targeted at code generation using tempo) is
based on EIEIO (which I wrote, so naturally I think it's cool.  FSF
even has papers for it.)

  The idea is that he has several classes the create and manage dialog
boxes using custom's widgets.  To make a specific dialog box, you can
inherit from a base class, and make a specific instance.  This whole
system is then wired into the `interactive' command to extra spiffy

  So, the long and short of it is the `markup language' would be Emacs
Lisp, but I doubt that would bum any Emacs hackers out.  If it does,
the FSF just so happens to have papers for my parser generator which
would be perfect for parsing a simple deterministic invented

  Not to bomb William Perry's efforts or anything, HTML is great at
this stuff too, and I like w3 in general.  Just another angle where
some solutions already exist.
