#
#  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
#
