The CGI source http://hoohoo.ncsa.uiuc.edu/cgi/ you mentioned yesterday is
the actual reference. There is no other format defined but as you find in
the examples section there are libraries ready to provide access to the
parameters. Actually it's been quite a while since I coded CGI's in shell.
Perl for example has a multitude of CGI interfaces available which take the
burden out of decoding the CGI stream.

Correct, but it would be a very central location and easy to maintain.

Sounds sensible
