** Desc      A CGI library for C programmers. Automatically handles GET, POST
**           and ISINDEX requests, with lots of useful routines to simplify
**           CGI development. Applications can even be debugged from the
**           commandline!
**
** Limits    Cannot yet handle form file uploads.
