# $NetBSD: check-files.mk,v 1.30 2014/02/20 09:15:15 obache Exp $
#
# This file checks that the list of installed files matches the PLIST.
# For that purpose it records the file list of LOCALBASE before and
# after the installation of the package and compares these lists with
# the PLIST.
#
# User-settable variables:
#
# CHECK_FILES
#	"yes" to enable the check, "no" to disable it.
#
#	Default value: "yes" for PKG_DEVELOPERs, "no" otherwise.
#
# CHECK_FILES_STRICT
#	When set to "yes", VARBASE and PKG_SYSCONFDIR are checked in
#	addition to LOCALBASE.
#
# Package-settable variables:
#
# CHECK_FILES_SKIP
#	A list of regular expressions (FIXME: all other checks use shell
#	patterns) that names files to be skipped. This is useful to
#	avoid getting errors triggered by changes in directories not
#	really handled by pkgsrc.
