I somewhat underestimated the response I would get for the above
message.  I've emailed the code to some of you, but there's still a
backlog, and there are some of you I couldn't reach.  There were
suggestions that I _post_ the code.  I guess, though, it'd be more
convenient to all concerned if I made it ftp'able from Rice, rather
than clog the net.

Procedure: ftp titan.rice.edu (as anonymous)
	   get public/slog.sh

slog.sh is a shar file, and contains two implementation files (slog.ss
and bagof.ss), two doc (loosely speaking!) files (Readme and Usage),
and a bunch of example files (mostly from Sterling&Shapiro) to make it
easy to acquire a feel for the possibly unusual syntax.  The code is
_not_ completely RRRS-compatible, but should be easily fixable for the
Scheme of your choice/fate by adding requisite definitions of
extend-syntax, boxes and printf (see The Scheme Programming Language
by R. Kent Dybvig).  If you encounter bugs/problems or get royally
chewed by you-don't-know-what, email me, and I'll see if I can fix it.

BTW, I would still like to get email from those who will be ftp'ing
the stuff, so that I can get back to you if there are changes.  (No,
the list of names will _not_ be released to junk-mail senders. :-)

ps: The code is completely free, and users can make all the changes
and/or extensions to it they want.  You might want to tell me about
it, if you think it's significant, though.
