See L<CPAN/"Plugin support">. =head1 METHODS =head2 plugin_requires returns list of packages given plugin requires for functionality. This list is evaluated using C<< CPAN->use_inst >> method. =head2 distribution_object Get current distribution object. =head2 distribution =head2 distribution_info =head2 build_dir Simple delegatees for misc parameters derived from distribution =head2 is_xs Predicate to detect whether package contains XS. =head1 AUTHOR Branislav Zahradnik <barney@cpan.org> =cut
