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
