I have uploaded Zen 1.0 to the submissions directories of
cs.orst.edu and nova.cc.purdue.edu. Zen is a simple
Scheme programming environment that incorporates 
Oliver Laumann's ELK Scheme interpreter. The application
includes a built-in NextStep editor and a Listener
window that communicates with the Scheme evaluator.

ELK is a very nice Scheme implementation, and I can't
take credit for it at all; the only modifications
I have made to it so far are to integrate it better
with the Zen application. It's much better than the 
interpreter that I wrote myself.

This first release is mostly devoid of whizzy features; 
it's just an editor and a Listener, with some handy
menu items thrown in. It is distributed as a file
package, and includes a brief Release Notes file, and
a somewhat lengthy WriteNow documentation file.

Zen is free, but copyrighted. The sources are not yet
available because I don't yet like them well enough.
If you use it, send me mail to let me know. If you
want features added, send me mail. If it fails to work
for any reason, send me mail.
