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.
