3815 Module::Build::Base - Default methods for Module::Build
3819 Please see the Module::Build documentation.
3823 The C<Module::Build::Base> module defines the core functionality of
3824 C<Module::Build>. Its methods may be overridden by any of the
3825 platform-dependent modules in the C<Module::Build::Platform::>
3826 namespace, but the intention here is to make this base module as
3827 platform-neutral as possible. Nicely enough, Perl has several core
3828 tools available in the C<File::> namespace for doing this, so the task
3829 isn't very difficult.
3831 Please see the C<Module::Build> documentation for more details.
