+=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.
