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
