Holland takes some pains to exit 0 on success and non-zero on failure.
 So checking the exit status is the standard way and how we monitor it
here, but we're usually firing it off via some process other than
cron.

In cron, I suppose we would just send an email or touch a file on a
non-zero exit status via something like:

holland backup [options] || echo "Failed backup" ...

We don't presently have anything more sophisticated than that in the
1.0 (stable) branch.
