Subject: got build + regress script for cron
To: gameoftrees@openbsd.org
Date: Sun, 8 Mar 2020 16:51:59 +0100

This is a script which updates a got worktree, compiles got and gotweb,
runs regression tests, and sends email if something went wrong.

I plan to run this from a cronjob on a sparc64 machine.

Any objections to having logs of failures mailed to this list?

Required dependencies: pkg_add got git kcgi lockfile
And sending email with 'mail -s ...' needs to work.
