# Mirrors the "Push & release my locks" button in the Unity Git Locks window.
#
# Installed as `git sync` by setup-git-locks.sh. Run it from anywhere inside the repo.
#
# A lock is released only if its file has a clean working tree (nothing uncommitted),
# i.e. the version on the server is the one you finished. Files you still have changes
# on keep their lock. Locks owned by other people are skipped (and the server enforces it anyway).
