# 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	"install*arch" directory under which packlist
#			files are installed; defaults to
#			${PERL5_INSTALLVENDORARCH}.
#
# PERL5_PACKLIST	list of packlist files relative to
#			${PERL5_PACKLIST_DIR}.
