|no dot dirs||
This distribution has a dot directory, which most probably derives from a version control system.
Fix MANIFEST (or MANIFEST.SKIP) to exclude dot directories from a distribution. Use an appropriate tool and avoid archiving your working directory by hand. If you switch your version control system, remove old VCS directories after you migrate.
This distribution is not required by another distribution by another author.
Convince / force / bribe another CPAN author to use this distribution.
Excellent. Your distribution passes all the experimental metrics.
