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

SYNOPSIS
	   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");
	       }
	   }

DESCRIPTION
       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

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

       errstr()
	   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.

LICENSING
       For support and licensing information see CGI::Session.
