SUMMARY = "Mozilla's SSL and TLS implementation"
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."
