4021 Module::Build::Base - Default methods for Module::Build
4025 Please see the Module::Build documentation.
4029 The C<Module::Build::Base> module defines the core functionality of
4030 C<Module::Build>. Its methods may be overridden by any of the
4031 platform-dependent modules in the C<Module::Build::Platform::>
4032 namespace, but the intention here is to make this base module as
4033 platform-neutral as possible. Nicely enough, Perl has several core
4034 tools available in the C<File::> namespace for doing this, so the task
4035 isn't very difficult.
4037 Please see the C<Module::Build> documentation for more details.
