Well it's quite simple actually. It's just a bunch of regexps that tag
log-lines as important / urgent / whatever.
And a cron job that greps these lines and decides when to mail them.
It's actually quite handy, as logs tend to become large, so reading
them dutifully every day isn't a real option.
Having them digested daily, grouped per kind of incident makes it a
1-minute task to skim through.
