        Manipulates network routing tables.
        ROUTE [-f] [-p] [-4|-6] command [destination]
                          [MASK netmask]  [gateway] [METRIC metric]  [IF interface]
          -f           Clears the routing tables of all gateway entries.  If this is
                       used in conjunction with one of the commands, the tables are
                       cleared prior to running the command.
          -p           When used with the ADD command, makes a route persistent across
                       boots of the system. By default, routes are not preserved
                       when the system is restarted. Ignored for all other commands,
                       which always affect the appropriate persistent routes.
          -4           Force using IPv4.
          -6           Force using IPv6.
          command      One of these:
                         PRINT     Prints  a route
                         ADD       Adds    a route
                         DELETE    Deletes a route
                         CHANGE    Modifies an existing route
          destination  Specifies the host.
          MASK         Specifies that the next parameter is the 'netmask' value.
          netmask      Specifies a subnet mask value for this route entry.
                       If not specified, it defaults to
          gateway      Specifies gateway.
          interface    the interface number for the specified route.
          METRIC       specifies the metric, ie. cost for the destination.
        All symbolic names used for destination are looked up in the network database
        file NETWORKS. The symbolic names for gateway are looked up in the host name
        database file HOSTS.
        If the command is PRINT or DELETE. Destination or gateway can be a wildcard,
        (wildcard is specified as a star '*'), or the gateway argument may be omitted.
        If Dest contains a * or ?, it is treated as a shell pattern, and only
        matching destination routes are printed. The '*' matches any string,
        and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*.
        Pattern match is only allowed in PRINT command.
        Diagnostic Notes:
            Invalid MASK generates an error, that is when (DEST & MASK) != DEST.
            Example> route ADD MASK IF 1
                     The route addition failed: The specified mask parameter is invalid.
         (Destination & Mask) != Destination.
            > route PRINT
            > route PRINT -4
            > route PRINT -6
            > route PRINT 157*          .... Only prints those matching 157*
            > route ADD MASK METRIC 3 IF 2
                     destination^      ^mask      ^gateway     metric^    ^
              If IF is not given, it tries to find the best interface for a given
            > route ADD 3ffe::/32 3ffe::1
            > route CHANGE MASK METRIC 2 IF 2
              CHANGE is used to modify gateway and/or metric only.
            > route DELETE
            > route DELETE 3ffe::/32
