# Perl script to convert a standard distribution directory for file 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 file by an
|
|
# order of magnitude (or more?)
|
|
#
|
|
# This script requires two environment variables set:
|
|
# SRCDIR - file source directory
|
|
# TARGETDIR - name of the high level directory to make
|
|
#
|
|
# Written by Christos Zoulas July 17, 1997 for file-3.26
