This distribution doesn't create a directory and extracts its content into this directory. Instead, it creates more than one directories (some of which are probably system-specific hidden files/directories), or it spews its content into the current directory, making it really hard/annoying to remove the unpacked package.
Pack the distribution with a proper command such as "make dist" and "./Build dist", or use a distribution builder such as Dist::Zilla, Dist::Milla, Minilla.
|no pax headers||
This distribution is archived with PAX extended headers, which may be useful under some environments, but may also make extraction fail under other environments (Archive::Tar ignores PAX information as well).
If you use Mac OS X >= 10.6, use gnu tar (/usr/bin/gnutar) to avoid PAX headers. It's also important to rename (shorten) long file names (>= 100 characters) in the distribution.
|meta yml declares perl version||
This distribution does not declare the minimum perl version in META.yml.
This distribution is not required by another distribution by another author.
Convince / force / bribe another CPAN author to use this distribution.
These fails are not serious and don't affect your Kwalitee scores at all.
|meta yml has provides||
This distribution does not have a list of provided modules defined in META.yml.
|has separate license file||
This distribution does not have a LICENSE or LICENCE file in its root directory.
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
