If you want to we could create a module for wiki-scsh in the sunet CVS
at SourceForge and add you to the developers of sunet.

Okay... I did not realize that wiki-scsh is a fairly new
implementation, because I overlooked the CVS dates within the
files. Sometimes in my lonely hours debugging scsh-0.6 I think no one
is using scsh at all nowadays ;-)

Of course I want to!

Yeah, now I've got it. Pretty cute... Maybe some documentation (your
lines above) in wiki-package would help ;-)
Ed> I hope this is helpful but if not let me know.
I am not that happy with the executable wiki you build. First some OS
(FreeBSD) have a limitation on the length of the #!-header and the way
you build wiki this is easily exceeded (My scsh lives in
/afs/informatik.uni-tuebingen.de/home/gasbichl/i386_fbsd40/scsh-0.6).
So a /bin/sh trampoline would be better, I think.
Second I cannot build wiki at Linux at all:
student14[35] make
scsh -lm wiki-lib.scm -lm wiki-package.scm \
-o changes -o edit -o refcount -o save -o search -o wiki \
-c '(dump-scsh "wiki.tmp")'
Writing wiki.tmp
echo '#!/usr/local/lib/scsh/scshvm \\\n-o /usr/local/lib/scsh/scshvm -i\n' | \
cat - wiki.tmp > wiki
rm wiki.tmp
chmod +x wiki
rm -f ../changes.cgi ../edit.cgi ../refcount.cgi ../save.cgi ../search.cgi
../wiki.cgi ../.tmpcgi
printf "#!/bin/sh\nexec %s -c \(\`basename \$0 .cgi\`\)" \
`pwd`/wiki > ../.tmpcgi
printf: \(: invalid escape
make: *** [CGI] Error 1
And for FreeBSD the first line of wiki looks like this:
#!/usr/local/lib/scsh/scshvm \\\n-o /usr/local/lib/scsh/scshvm -i\n
which is probably not what you intended...
