This is the start of a test jig for Pluto.

You should add `pwd`/bin to PATH.  It contains the testing scripts.

bin/CONFIG specifies configuration details for all the scripts.  At a
minimum, you must specify where to find the binaries for pluto and
whack (you can set environment variables rather than editing
bin/CONFIG).

Since the testing uses information from the Domain Name System, a
couple of zones must be added to the name server:  test.zone and
test.rev.zone.  Each of these zone files includes comments as to what
changes need to be made to /etc/named.conf.

The only script that needs superuser privileges is bin/ifconfigs.  This
sets up aliases to interface lo for testing.  It can also be used to
remove these aliases.  Since the setup persists, "ifconfigs up" only
needs to be redone after a system reboots (or something else drastic).

bin/doauto runs all current tests.  Output is captured in
subdirectories under log/.  The whack portion of the output is
compared with that captured under log.ref/.  We don't yet distribute a
sample log.ref.

Example of a test (run in this directory):

	export PATH=$PATH:`pwd`/bin
	su -c "ifconfigs up"
	export PLUTO=../../programs/pluto/pluto
	export WHACK=../../programs/pluto/whack
	doauto
