 This is FreeSec package for NetBSD,  unchanged for
 FreeBSD, except for the Makefile.
 
-The other stuff in libcrypt will be added in stages!
+FreeSec was written by David Burren <davidb@werj.com.au>
+
+A few bugs in the original FreeSec release have been fixed.
+
+In order to make libcrypt binaries exportable from the USA,
+only the symbol _crypt() (later to be changed to ___crypt())
+is exported from libcrypt.
+
+This source code was developed outside the USA, and can be
+obtained outside the USA.
