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