A puppet-lint extension that offers warnings when you include words that have a racist history: 'master/slave', 'whitelist/blacklist', for starters. See: https://www.ietf.org/archive/id/draft-knodel-terminology-13.txt
This check will not match against URL's. This is by design to not flag for every comment that may contain a github link to a repo using 'master' as the main branch.
