I was having thoughts about taking it a step further - having an rc.d/
type directory of scripts to run after the checkout. By default, this
would just be the " cvs diff | mail " command, but I can see it being
useful for other things as well - say, for running a "rat" report any
time there are router changes, or re-drawing the network diagram (if
you're the kind of person that generates this from the config files).

A different way to solve the parent's problem would be to use diff's
'--exclude-from=FILE' argument. On this list previously, we've had
people wanting to suppress Cisco Call Manager forwarding changes, as
well as spantree changes on some Catalyst switches.
