# Set up for an Ubuntu package build.
#
# This is a script because we need to set the changelog, and some day
# we may need to do something about filtering specific files so we can
# use the same skeleton for both Ubuntu and Debian builds without
# requiring them to be identical.
#
# For now, though, this just copies the debian skeleton and creates a
# changelog.
