Cisco config checker

for two+ years, i have been asking cisco for a simple text-based tool that
can take two configs and generate the command set to get from the first to
the second.  i.e. a semantic differ.

as syntax (and occasionally semantics) changes release to release, a version
of the code would have to come with each image set.

note that this would go a way to compete with the really nice behavior of
gated-like systems, e.g. juniper, which, when given a new configuration,
does not thrash all your bgp sessions etc., but slides smoothly to the new
