3 * whatnowproc.c -- exec the "whatnowproc"
12 * This routine is used by comp, repl, forw, and dist to exec
13 * the "whatnowproc". It first sets up all the environment
14 * variables that the "whatnowproc" will need to check, and
15 * then execs the command. As an optimization, if the
16 * "whatnowproc" is the nmh command "whatnow" (typical case),
17 * it will call this routine directly without exec'ing it.
