/*
 * As there's no documnented way of executing script on MPW, we just write commands to the
 * standard output.
 *
 * External routines:
 *	execcmd() - launch an async command execution
 * 	execwait() - wait and drive at most one execution completion
 *
 * Internal routines:
 *	onintr() - bump intr to note command interruption
 *
 * 04/08/94 (seiwald) - Coherent/386 support added.
 * 05/04/94 (seiwald) - async multiprocess interface
 * 01/22/95 (seiwald) - $(JAMSHELL) support
 * 01/20/00 (seiwald) - Upgraded from K&R to ANSI C
