/*
 *	newsgate.h
 *
 *	This file contains the definitions needed for the notesfile/news
 *	gateway features.
 *
 *	The new (April 4) implementation allows gateing from news to 
 *	notesfiles at ANY site. Gateing from notes to news is allowed 
 *	by a SINGLE site (for any given newsgroup) per notesfile 'subnet'.
 *
 *	An example:
 *	4 sites running notesfiles: A,B,C and D.
 *
 *	Both A and B run news alongside the notesfile program.
 *	A and B both gateway news into notesfiles; this is safe
 *	and does not generate duplicate articles.
 *	Neither C nor D run news; they do want the articles they
 *	have written to go to the news system beyond A and B.
 *	Sites A and B should at least gateway their locally generated
 *	articles to news.  Sites C and D should each make their own
 *	arrangements to have their articles passed to the news
 *	networks.  Good criteria for choosing the site include
 *	the load of the machine to gateway, how well it is connected
 *	to the rest of the network and who runs the machine.
 *	In this case, suppose C goes with A and D goes with B.
 *	The gateway scripts will look something like:
 *
 *	On A:
 *		newsoutput list			(local articles (A))
 *		newsoutput -sC list		(C's articles)
 *
 *	On B:
 *		newsoutput list			(local articles (B))
 *		newsoutput -sD list		(D's articles)
 *
 *
 *	Original Coding:	Ray Essick	April 4, 1982
