Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.
- MANIFEST (13) does not match dist (12):
- Missing in Dist: lib/HTML/ChunksLocal.pm
List all used modules in META.yml requires
Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.
Error: HTML-Chunks/lib/HTML/Chunks/Local.pm -- Around line 115: You forgot a '=back' before '=head1'
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
Error: HTML::Chunks, HTML::Chunks::Local, HTML::Chunks::Super
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
