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.
