DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
     The input for ttttccccpppp----eeeennnnvvvv must be  a  TCP  connection.   ttttccccpppp----eeeennnnvvvv
     finds out information about that connection, puts the infor-
     mation into several environment variables  as  described  in
     ttttccccpppp----eeeennnnvvvviiiirrrroooonnnn((((5555)))),,,, and runs _p_r_o_g_r_a_m with the given arguments.

     Usually ttttccccpppp----eeeennnnvvvv is run from iiiinnnneeeettttdddd.  It might instead be  run
     from  another server that already sets up the right environ-
     ment variables; if PPPPRRRROOOOTTTTOOOO is  set  to  TTTTCCCCPPPP  when  ttttccccpppp----eeeennnnvvvv  is
     invoked,  ttttccccpppp----eeeennnnvvvv  assumes  that all the other variables are
     set up properly, and it does not check whether the input  is
     a TCP connection.
