#	Script to grab linux-HA from CVS, build it, and
#	run BasicSanityCheck on it...
#
#	Certain parts of this script need superuser permissions.
#	We use sudo for these.  For convenience we do something with sudo
#	right at the first, and to avoid getting timed out on the password
#	we do something gratuitous with sudo before/after commands that take
#	a while...  It works for me... YMMV ;-)
