+define Package/refpolicy/description
+	The SELinux Reference Policy project (refpolicy) is a
+	complete SELinux policy that can be used as the system
+	policy for a variety of systems and used as the basis for
+	creating other policies. Reference Policy was originally
+	based on the NSA example policy, but aims to accomplish many
+	additional goals.
+
+	The current refpolicy does not fully support OpenWRT and
+	needs modifications to work with the default system file
+	layout. These changes should be added as patches to the
+	refpolicy that modify a single SELinux policy.
+
+	The refpolicy works for the most part in permissive
+	mode. Only the basic set of utilities are enabled in the
+	example policy config and some of the pathing in the
+	policies is not correct.  Individual policies would need to
+	be tweaked to get everything functioning properly.
