COMPATIBILITY WITH CGI-LIB.PL

To make it easier to port existing programs that use cgi-lib.pl the compatibility routine ``ReadParse'' is provided. Porting is simple:

OLD VERSION require ``cgi-lib.pl''; &ReadParse; print ``The value of the antique is $in{antique}.\n'';

NEW VERSION use CGI; CGI::ReadParse print ``The value of the antique is $in{antique}.\n'';

CGI.pm's ReadParse routine creates a tied variable named %in, which can be accessed to obtain the query variables. Like ReadParse, you can also provide your own variable. Infrequently used features of ReadParse, such as the creation of @in and $in variables, are not supported.

Once you use ReadParse, you can retrieve the query object itself this way: 

    $q = $in{CGI};
    print $q->textfield(-name=>'wow',
			-value=>'does this really work?');

This allows you to start using the more interesting features of CGI.pm without rewriting your old scripts from scratch.
