Module::cpants::analyse is a utility module used by test::kwalitee and others to analyse cpan distributions and determine their kwalitee. kwalitee is a set of software metrics useful for determine how good your software is; it's not true software quality, which your computer can't measure in a general sense. (if you can, you've solved a hard problem in computer science.)

kwalitee looks like quality, sounds like quality, but it's not quite quality. if you plan to release a distribution to the cpan -- or even within your own organization -- testing its kwalitee before creating a release can help you improve your quality as well.
