configure

#!/bin/sh
#
# This is the bootstrapping configuration script for Ganymede. The
# only thing we count on to run this script is that /bin/sh works.
#
# Get enough information from the user to be able to find Perl 5 and
# run scripts/configurator.perl.  We'll set a bunch of environment variables
# for configurator.perl to use to do its thing.
