SYNOPSIS

       spipe dir1 dir2 ...

DESCRIPTION

       spipe  is  designed  for  the purpose of allowing supervise to manage a
       complete pipeline of commands.  spipe executes supervise on all of  the
       named  directories,  inserting  a  pipe between each pair of supervised
       processes.  The supervise processes are started from last to first,  to
       ensure that each producer of output has a consumer to pipe its data to.
       If spipe is sent either the INT, QUIT, or the TERM signal, it runs  svc
       -dx  on  each  command  to shut it down, and waits for it to exit.  The
       processes are shut down from first to last, to ensure  that  each  pro-
       ducer  stops  writing its output before shutting down the corresponding
       consumer.

RETURN VALUE

       Exits 0 when all the commands are shut  down.   If  a  fatal  error  is
       encountered, it exits.
