+	  AppArmor is an effective and easy-to-use Linux application
+	  security system. AppArmor proactively protects the operating
+	  system and applications from external or internal threats,
+	  even zero-day attacks, by enforcing good behavior and
+	  preventing even unknown application flaws from being
+	  exploited.
+
+	  This package installs only the library.
