+define Package/libselinux/description
+	libselinux is the runtime SELinux library that provides
+	interfaces (e.g. library functions for the SELinux kernel
+	APIs like getcon(), other support functions like
+	getseuserbyname()) to SELinux-aware applications. libselinux
+	may use the shared libsepol to manipulate the binary policy
+	if necessary (e.g. to downgrade the policy format to an
+	older version supported by the kernel) when loading policy.
