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.
