# $NetBSD: packlist.mk,v 1.20 2018/01/07 11:40:57 rillig Exp $
#
# This Makefile fragment is intended to be included by packages that
# create packlist files.  This file is automatically included by
# perl5/module.mk, so it is typically not necessary to include this
# file.
#
# The following variables should be set prior to including this file:
#
# PERL5_USE_PACKLIST
#	When set to "yes" (the default), automatically generates the
#	PLIST for the pkgsrc package from the Perl packlist.
#
# PERL5_PACKLIST_DIR
#	The "install*arch" directory under which packlist files are
#	installed. Only needs to be overridden in very special cases.
#
#	Default: ${PERL5_INSTALLVENDORARCH}
#
# PERL5_PACKLIST
#	The list of packlist files relative to ${PERL5_PACKLIST_DIR}.
#
#	Example: .auto/Text/Trim/.packlist
