           (NIS) Sun Microsystems' Yellow Pages
          (yp) client-server protocol for distributing system
          configuration data such as user and host names between
          computers on a network.
       
          Sun licenses the technology to virtually all other Unix
          vendors.
       
          The name "Yellow Pages" is a registered trademark in the
          United Kingdom of British Telecommunications plc for their
          (paper) commercial telephone directory.  Sun changed the name
          of their system to NIS, though all the commands and functions
          still start with "yp", e.g. ypcat, ypmatch, ypwhich.
       
          Unix manual pages: yp(3), ypclnt(3), ypcat(1), ypmatch(1).
