Migrating A Formula To A Tap

There are times when we may wish to migrate a formula from one tap into another tap. To do this:

1. Create a pull request to the new tap adding the formula file as-is from the original tap. Fix any test failures that may occur due to the stricter requirements for new formulae than existing formula (e.g. brew audit --strict must pass for that formula).
2. Create a pull request to the original tap deleting the formula file and add it to tap_migrations.json with a commit message like gv: migrate to homebrew/core.
3. Put a link for each pull request in the other pull request so the maintainers can merge them both at once.

Congratulations, you've moved a formula to a tap!
