#
# Perl script to convert a standard distribution directory for tcpdump 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 tcpdump by an
# order of magnitude (or more?)
#
# This script requires two environment variables set:
# SRCDIR - tcpdump source directory
# TARGETDIR - name of the high level directory to make
#
# Written by Christos Zoulas Oct 2nd, 1997 for tcpdump-3.4a5
#
$version = "3.4a5";
# definitions ...
