1 /*******************WARNING********************* 2 3 This is a *MODIFIED* version of Geoff Coller's proof-of-concept NOV 4 implementation. 5 6 It has been modified to support threading directly from a file handle 7 to a NNTP server without a temporary file. 8 9 This is not a complete distribution. We have only distributed enough 10 to support NN's needs. 11 12 The original version came from world.std.com:/src/news/nov.dist.tar.Z 13 and was dated 11 Aug 1993. 14 15 In any case, bugs you find here are probably my fault, as I've trimmed 16 a fair bit of unused code. 17 18 -Peter Wemm <peter@DIALix.oz.au> 19 */ 20 21 /* 22 * Copyright (c) Geoffrey Collyer 1992, 1993. 23 * All rights reserved. 24 * Written by Geoffrey Collyer. 25 * Thanks to UUNET Communications Services Inc for financial support. 26 * 27 * This software is not subject to any license of the American Telephone 28 * and Telegraph Company, the Regents of the University of California, or 29 * the Free Software Foundation. 30 * 31 * Permission is granted to anyone to use this software for any purpose on 32 * any computer system, and to alter it and redistribute it freely, subject 33 * to the following restrictions: 34 * 35 * 1.
