       $class\::Const - Perl Interface for $class Constants

SYNOPSIS
CONSTANTS

NAME
       ModPerl::Code - Generate mod_perl glue code

SYNOPSIS
         use ModPerl::Code ();
         my $code = ModPerl::Code->new;
         $code->generate;

DESCRIPTION
       This module provides functionality for generating mod_perl glue code.  Reason this code is generated
       rather than written by hand include:

       consistency
       thin and clean glue code
       enable/disable features (without #ifdefs)
       adapt to changes in Apache
       experiment with different approaches to gluing
