Thank you for the link. It contains this tiny gem: a glimpse into a path that CGI applications have not taken:<p>&gt; CGI programs should accept these as command-line options, and also if given as the PATH_INFO; for instance, visiting ‘<a href="http:&#x2F;&#x2F;example.org&#x2F;p.cgi&#x2F;--help’" rel="nofollow">http:&#x2F;&#x2F;example.org&#x2F;p.cgi&#x2F;--help’</a> in a browser should output the same information as invoking ‘p.cgi --help’ from the command line.
