+/*
+ * 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
