+# This is somewhat nonintuitive.  In English:

+#	For any action of type "set",
+#	if the "name" property matches the regex "variant.arch",
+#	and *every* occurrence of the "value" property does not match
+#		$ARCH, then don't publish it.
+#
+# ...in other words, if *any* occurrence of "value" matches $(ARCH),
+# then the negative lookahead assertion in the regex will fail, and we
+# won't abort based on the action.
