Description:
RFC documents metapackage
RFC (Request for Comments) documents are a series of technical and organizational notes about the Internet. They are edited by the Internet Engineering Task Force (IETF). . This is a metapackage that pulls in the new doc-rfc-xxx packages (those that most closely correspond to the old doc-rfc package). . It can be removed if users want just a subset of the RFCs.
