+// Package auth implements an access control model that is a subset of Linux's.
+//
+// The auth package supports two kinds of access controls: user/group IDs and
+// capabilities. Each resource in the security model is associated with a user
+// namespace; "privileged" operations check that the operator's credentials
+// have the required user/group IDs or capabilities within the user namespace
+// of accessed resources.
