3 * whatnowproc.c -- exec the "whatnowproc"
5 * This code is Copyright (c) 2002, by the authors of nmh. See the
6 * COPYRIGHT file in the root directory of the nmh distribution for
7 * complete copyright information.
14 * This routine is used by comp, repl, forw, and dist to exec
15 * the "whatnowproc". It first sets up all the environment
16 * variables that the "whatnowproc" will need to check, and
17 * then execs the command. As an optimization, if the
18 * "whatnowproc" is the nmh command "whatnow" (typical case),
19 * it will call this routine directly without exec'ing it.
