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