This is Stelligent's homebrew tap. Formulas should go in here.
This GitHub Action will execute update_cfn_nag_formula_version.sh modify the cfn-nag.rb file with the latest cfn_nag and requirements versions and commit them to this repo so they are available in Homebrew. It's triggered by a repository_dispatch event from the stelligent/cfn_nag repo's workflow when commits are merged to the master branch.
