Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install L<Dist::Zilla>, L<Dist::Zilla::PluginBundle::Author::PERLANCAR>, L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me. =head1 COPYRIGHT AND LICENSE This software is copyright (c) 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012 by perlancar <perlancar@cpan.org>.
