NAME

       AppConfig::CGI - Perl5 module for processing CGI script parameters.

SYNOPSIS

           use AppConfig::CGI;

           my $state = AppConfig::State->new(\%cfg);
           my $cgi   = AppConfig::CGI->new($state);

           $cgi->parse($cgi_query);
           $cgi->parse();               # looks for CGI query in environment

OVERVIEW

       AppConfig::CGI is a Perl5 module which implements a CGI interface to AppConfig.  It
       examines the QUERY_STRING environment variable, or a string passed explicitly by
       parameter, which represents the additional parameters passed to a CGI query.  This is then
       used to update variable values in an AppConfig::State object accordingly.

       AppConfig::CGI is distributed as part of the AppConfig bundle.

DESCRIPTION

   USING THE AppConfig::CGI MODULE
       To import and use the AppConfig::CGI module the following line should appear in your Perl
       script:

           use AppConfig::CGI;

       AppConfig::CGI is used automatically if you use the AppConfig module and create an
       AppConfig::CGI object through the cgi() method.  AppConfig::CGI is implemented using
       object-oriented methods.  A new AppConfig::CGI object is created and initialised using the
       new() method.  This returns a reference to a new AppConfig::CGI object.  A reference to an
       AppConfig::State object should be passed in as the first parameter:

           my $state = AppConfig::State->new();
           my $cgi   = AppConfig::CGI->new($state);

       This will create and return a reference to a new AppConfig::CGI object.

   PARSING CGI QUERIES
       The "parse()" method is used to parse a CGI query which can be specified explicitly, or is
       automatically extracted from the "QUERY_STRING" CGI environment variable.  This currently
       limits the module to only supporting the GET method.

       See AppConfig for information about using the AppConfig::CGI module via the cgi() method.
