- * 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.
