+
+  I wrote this webserver for an assignment in my networking class in
+1999.  We were told that at a bare minimum the server had to serve
+pages, and told that we would get extra credit for doing "extras."
+Perl had introduced me to a whole lot of UNIX functionality (I learned
+sockets and fork from Perl!), and O'Reilly's lion book on UNIX system
+calls plus O'Reilly's books on CGI and writing web clients in Perl got
+me thinking and I realized I could make my webserver support CGI with
+little trouble.
+
+  Now, if you're a member of the Apache core group, you might not be
+impressed.  But my professor was blown over.  Try the color.cgi sample
+script and type in "chartreuse."  Made me seem smarter than I am, at
+any rate. :)
+
+  Apache it's not.  But I do hope that this program is a good
+educational tool for those interested in http/socket programming, as
+well as UNIX system calls.  (There's some textbook uses of pipes,
+environment variables, forks, and so on.)
+
+  One last thing: if you look at my webserver or (are you out of
+mind?!?) use it, I would just be overjoyed to hear about it.  Please
+email me.  I probably won't really be releasing major updates, but if
+I help you learn something, I'd love to know!
+
+  Happy hacking!
