post-commit — Notification of a successful commit.
post-commit hook is run after the
transaction is committed and a new revision is created. Most
people use this hook to send out descriptive emails about
the commit or to notify some other tool (such as an issue
tracker) that a commit has happened. Some configurations
also use this hook to trigger backup processes.
post-commit hook returns a

not be aborted since it has already
completed. However, anything that the hook printed

client, making it easier to diagnose hook failures.
