# $NetBSD: bsd.pkg.check.mk,v 1.7 2005/07/15 18:27:54 jlam Exp $
#
# This Makefile fragment is included by bsd.pkg.mk and defines the
# relevant variables and targets the for various install-time "check"
# targets.
#
# The following variables may be set by the user and control which
# checks are run:
#
#    CHECK_FILES causes the extra or missing file checks to be run if
#	it is any value other than "no".  Defaults to "no".
#
#    CHECK_FILES_STRICT makes the file checks very strict on errors if
#	it is any value other than "no".  Defaults to "no".
#
#    CHECK_WRKREF is a list of options that trigger the checks for
#	${WRKDIR} or ${TOOLS_DIR} in the package's installed files.
#	Valid values are "work", which checks for ${WRKDIR}, and
#	"tools", which checks for ${TOOLS_DIR}.  Defaults to "no".
#
# The following targets are defined by bsd.pkg.check.mk:
#
#    check-files-pre & check-files-post generate the list of files on the
#	filesystem just before and just after the package's files are
#	installed.
#
#    check-files compares the "pre" and "post" file lists to determine
#	if there are any extra or missing files installed by the
#	package.
#
#    check-wrkref checks whether a package's installed files contain
#	references to ${WRKDIR}.
#

# For PKG_DEVELOPERs, cause some checks to be run automatically by default.
