 * Abstract:
 *	Establish basic operating environment for SPO256-AL2 text-to-speech
 *	server.  This module verifies system configuration, parses the
 *	config files for word lists that are stored in the quick-lookup
 *	internal hash word subsitution database, binds the server to a tcp
 *	network port, and accepts client requests.
