Cool. I'll look over it.

I haven't made a start yet, so I have no repo to share.

These two lines are unnecessary. The script will exit with the exit code
of the last command run.

However I find it safer to add a "set -e" to the top of the script so that
it will terminate early if any of the commands fail. This stops the script
proceeding based on previous incomplete operations. With "set -e" the script
will exit with the error code of the command that failed.

Those angled brackets in the URL look wrong. Does that really work?

Ditto here.
