Workflow file for this run

name: Style Checker
# Runs my simple style(9) checker on any pushes or pull requests. It could be
# optimized by fetching the pull request head branch back to main revisions and
# running on that. That would reduce the run time from 3-4 minutes down to 30-40
# seconds. Getting the right series of clone + fetches to get that iteratively
# is proving elusive, so optimizations welcome.
