       CGI::Session::ErrorHandler - error handling routines for CGI::Session

	   require CGI::Session::ErrorHandler
	   @ISA = qw( CGI::Session::ErrorHandler );

	   sub some_method {
	       my $self = shift;
	       unless (	 $some_condition ) {
		   return $self->set_error("some_method(): \$some_condition isn't met");

       CGI::Session::ErrorHandler provides set_error() and errstr() methods
       for setting and accessing error messages from within CGI::Session's
       components. This method should be used by driver developers for
       providing CGI::Session-standard error handling routines for their code

	   Implicitly defines $pkg_name::errstr and sets its value to
	   $message. Return value is always undef.

	   Returns whatever value was set by the most recent call to
	   set_error(). If no message as has been set yet, the empty string is
	   returned so the message can still concatenate without a warning.

       For support and licensing information see CGI::Session.
