When moving to commit, this hook will automatically fire and check the current system's installed packages against those explicitly committed to the repository. If they mismatch it will inform the user. It will not prevent the commit, but simply add a comment at the top of the commit messages to remind the user that something is unbalanced between both. It would be recommended to either check the additional package into source control, remove it from the current system, or explicitly add it to ignored packages.
