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

SYNOPSIS

CONSTANTS
EOF

  ":$group"
  use $class\::Const -compile qw(:$group);

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
