New contributed code

[shivers@ai.mit.edu (Olin Shivers)]

Scott Draves and Jonathan Rees' markup system is now available in
the scsh contributed code directory
        ftp://ftp-swiss.ai.mit.edu/pub/scsh/contrib

Markup is an extensible text markup system written in Scheme 48.
It currently has HTML and LaTeX back-ends. 

Got a nice hack you'd like to share? Send me the code or a URL.

Anybody want to volunteer to rewrite the scsh manual in markup or
SGML?
