      NAME
           services - service name data base

      DESCRIPTION
           The services file contains information regarding the known
           services available in the DARPA Internet.  For each service,
           a single line should be present with the following
           information:

           official service name
           port number
           protocol name
           aliases

           Items are separated by any number of blanks and/or tab
           characters.  The port number and protocol name are
           considered a single item; a ``/'' is used to separate the
           port and protocol (e.g. ``512/tcp'').  A ``#'' indicates a
           comment line.

           Service names may contain any printable character other than
           a field delimiter, newline, or comment character.
