=head1 NAME
Module::Build::Base - Default methods for Module::Build
=head1 SYNOPSIS
Please see the Module::Build documentation.
=head1 DESCRIPTION
The C<Module::Build::Base> module defines the core functionality of
C<Module::Build>. Its methods may be overridden by any of the
platform-dependent modules in the C<Module::Build::Platform::>
namespace, but the intention here is to make this base module as
platform-neutral as possible. Nicely enough, Perl has several core
tools available in the C<File::> namespace for doing this, so the task
isn't very difficult.
Please see the C<Module::Build> documentation for more details.
