128019Sjoerg/* 228021Sjoerg * Powerdog Industries kindly requests feedback from anyone modifying 328021Sjoerg * this function: 428021Sjoerg * 528021Sjoerg * Date: Thu, 05 Jun 1997 23:17:17 -0400 628021Sjoerg * From: Kevin Ruddy <kevin.ruddy@powerdog.com> 728021Sjoerg * To: James FitzGibbon <james@nexis.net> 828021Sjoerg * Subject: Re: Use of your strptime(3) code (fwd) 928021Sjoerg * 1028021Sjoerg * The reason for the "no mod" clause was so that modifications would 1128021Sjoerg * come back and we could integrate them and reissue so that a wider 1228021Sjoerg * audience could use it (thereby spreading the wealth). This has 1328021Sjoerg * made it possible to get strptime to work on many operating systems. 1428021Sjoerg * I'm not sure why that's "plain unacceptable" to the FreeBSD team. 1528021Sjoerg * 1628021Sjoerg * Anyway, you can change it to "with or without modification" as 1728021Sjoerg * you see fit. Enjoy. 1828021Sjoerg * 1928021Sjoerg * Kevin Ruddy 2028021Sjoerg * Powerdog Industries, Inc. 2128021Sjoerg */ 2228021Sjoerg/* 2328019Sjoerg * Copyright (c) 1994 Powerdog Industries.
