#
# 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 list of directory names that must not appear in installed files.
#
#	* "tools" for the tool wrapper directory
#	* "home" for FAKEHOMEDIR
#	* "wrksrc" for WRKSRC
#	* "work" for WRKDIR
#	* "wrkobjdir" for WRKOBJDIR
#	* "pkgsrc" for PKGSRCDIR
#	* "extra" for CHECK_WRKREF_EXTRA_DIRS
#
#	Default value: "tools" for PKG_DEVELOPERs, "no" otherwise.
#
# CHECK_WRKREF_EXTRA_DIRS
#	A list of additional directories (or other strings) that must
#	not appear in the installed files. For pbulk builds, the
#	location where the pbulk tools are installed should be added
#	here.
#
# Package-settable variables:
#
# CHECK_WRKREF_SKIP
#	The list of filename patterns that should be excluded from this
#	test, either absolute or relative to PREFIX.
