# Creates a pull request with the new version of a formula.
#
# Usage: brew bump [options...] <formula-name>
#
# Requires either `--url` and `--sha256` or `--tag` and `--revision`.
#
# Options:
# --dry-run: Print what would be done rather than doing it.
# --devel: Bump a `devel` rather than `stable` version.
# --url: The new formula URL.
# --sha256: The new formula SHA-256.
# --tag: The new formula's `tag`
# --revision: The new formula's `revision`.
