Well, the problem is really that we don't hear so much of these things
here in Europe. I wouldn't be all surprised if there already was a CLUE
supporting system ready and running. And, yes, I do have more specific
questions in mind:

- How are the CLUE project progressing and what more specifically *is*
the CLUE project?
- They say CLOS in the form of PCL is included in the Lisp Users packages
for Lyric, which we haven't got yet (but will have in a few weeks, I hope).
Is that true, and is there any difference between CLOS and PCL and is
CLOS an accepted standard and...
- What *is* CLUE and what *is* CLX? Is there any paper describing them?
I had not heard of them until I read some article on the net.

I really like the Xerox Lisp environment, but it would be *very* nice
to be able to write portable programs. A window system standard is
therefore absolutely necessary. I think there are a number of
application writers that are just waiting for this. Common Lisp was
a step forward, but as I/O is the most important part of a program
there really is a great need for CLUE, CLX or whatever.
