# $NetBSD: pidentd2netbsd,v 1.1 1998/07/15 07:37:26 msaitoh Exp $
#
# Perl script to convert a standard distribution directory for pidentd into
# a NetBSD source tree.
#
# This is done as a script so that as each distribution is released,
# only changes from the previous one need to be dealt with as
# modifications to this script and related files. This should
# reduce the cost of updating from a new release of pidentd by an
# order of magnitude (or more?)
#
# This script requires two environment variables set:
# SRCDIR - pidentd source directory
# TARGETDIR - name of the high level directory to make
#
# Written by SAITOH Masanobu July 1st, 1998 for pidentd-2.8.3
