|has meta yml||
The file "META.yml" is missing from this distribution. META.yml is needed by people maintaining module collections (like CPAN), for people writing installation tools, or just people who want to know some stuff about a distribution before downloading it.
Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
|manifest matches dist||
MANIFEST does not match the contents of this distribution.
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.
This distribution does not 'use strict;' (or its equivalents) in all of its modules. Note that this is not about the actual strictness of the modules. It's bad if nobody can tell whether the modules are strictly written or not, without reading the source code of your favorite clever module that actually enforces strictness. In other words, it's bad if someone feels the need to add 'use strict' to your modules.
Add 'use strict' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.
|no pod errors||
|prereq matches use||
This distribution uses a module or a dist that's not listed as a prerequisite.
List all used modules in META.yml requires
This distribution has .pm files with inconsistent versions.
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
|meta yml has license||
This distribution does not have a license defined in META.yml.
This distribution is not required by another distribution by another author.
Convince / force / bribe another CPAN author to use this distribution.
|no invalid versions||
This distribution has .pm files with an invalid version.
Fix the version numbers so that version::is_lax($version) returns true.
Excellent. Your distribution passes all the experimental metrics.
