4014 Module::Build::Base - Default methods for Module::Build
4018 Please see the Module::Build documentation.
4022 The C<Module::Build::Base> module defines the core functionality of
4023 C<Module::Build>. Its methods may be overridden by any of the
4024 platform-dependent modules in the C<Module::Build::Platform::>
4025 namespace, but the intention here is to make this base module as
4026 platform-neutral as possible. Nicely enough, Perl has several core
4027 tools available in the C<File::> namespace for doing this, so the task
4028 isn't very difficult.
4030 Please see the C<Module::Build> documentation for more details.
