SYNOPSIS

CONSTANTS

       The ":$group" group is for XXX 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
