# This file checks that the installed files don't contain any strings
# that point to the directory where the package had been built, to make
# sure that the package still works after the source code has been
# cleaned up.
#
# User-settable variables:
#
# CHECK_WRKREF:
#	The kind of directory that must not appear in installed files.
#
#	* "no" to disable this check at all
#	* "tools" for the tool wrapper directory
#	* "work" for WRKDIR
#	* "wrkobjdir" for WRKOBJDIR
#
#	Default value: "tools" for PKG_DEVELOPERs, "no" otherwise.
#
# Package-settable variables:
#
# CHECK_WRKREF_SKIP:
#	The list of filename patterns that should be excluded from this
#	test, either absolute or relative to PREFIX.
