=head1 NAME
Module::Build::Pluggable - Module::Build meets plugins
=head1 SYNOPSIS
use Module::Build::Pluggable (
'Repository',
'ReadmeMarkdownFromPod',
'PPPort',
);
my $builder = Module::Build::Pluggable->new(
... # normal M::B args
);
$builder->create_build_script();
=head1 DESCRIPTION
Module::Build::Pluggable adds pluggability for Module::Build.
=head1 HOW CAN I WRITE MY OWN PLUGIN?
Module::Build::Pluggable call B<HOOK_prepare> on preparing arguments for C<< Module::Build->new >>, B<HOOK_configure> on configuration step, and B<HOOK_build> on build step.
That's all.
And if you want a help, you can use L<Module::Build::Pluggable::Base> as base class.
