=head1 DESCRIPTION

Module for handling the wierdness that entails when you move from normal cgi scripting into the wonderful world of mod_perl.

The mod_perl object needs to know which response handler is being used.  This is a manditory argument.

Sessions are saved in a cleanup handler by default, as well as when the Lazy object is destroyed.  (call me paranoid)  If you wish to disable the mod_perl handler save, set saveOnCleanup => 0.  If it's not set, it's the same as if it was set to 1.

=head1 METHODS

=head2 _sessionCleanup

Mod_perl cleanup handler for saving session data.  Called automatically if using both mod_perl and session plugins.

=head2 new ( q )

Constructor.

=head3 q

CGI::Lazy object

=head2 vars ()

Returns mod_perl object settings from config.
