define Package/libnss/description
  Network Security Services (NSS) is a set of libraries designed to support
  cross-platform development of security-enabled client and server applications.
  Applications built with NSS can support SSL v2 and v3, TLS, PKCS 5, PKCS 7,
  PKCS 11, PKCS 12, S/MIME, X.509 v3 certificates, and other security standards.
