2.15. MT19937
   A C-program for MT19937, with initialization improved 2002/2/10.
   Coded by Takuji Nishimura and Makoto Matsumoto.
   This is a faster version by taking Shawn Cokus's optimization,
   Matthe Bellew's simplification, Isaku Wada's real version.

   Before using, initialize the state by using init_genrand(seed)
   or init_by_array(init_key, key_length).

2.18. OpenSSH
The licences which components of this software fall under are as
follows.  First, we will summarize and say that all components
are under a BSD licence, or a licence more free than that.

OpenSSH contains no GPL code.

1)
     * Copyright (c) 1995 Tatu Ylonen <ylo@cs.hut.fi>, Espoo, Finland
     *                    All rights reserved
     *
     * As far as I am concerned, the code I have written for this software
     * can be used freely for any purpose.  Any derived versions of this
     * software must be clearly marked as such, and if the derived work is
     * incompatible with the protocol description in the RFC file, it must be
     * called by a name other than "ssh" or "Secure Shell".

    [Tatu continues]
     *  However, I am not implying to give any licenses to any patents or
     * copyrights held by third parties, and the software includes parts that
     * are not under my direct control.  As far as I know, all included
     * source code is used in accordance with the relevant license agreements
     * and can be used freely for any purpose (the GNU license being the most
     * restrictive); see below for details.

    [However, none of that term is relevant at this point in time.  All of
    these restrictively licenced software components which he talks about
    have been removed from OpenSSH, i.e.,

     - RSA is no longer included, found in the OpenSSL library
     - IDEA is no longer included, its use is deprecated
     - DES is now external, in the OpenSSL library
     - GMP is no longer used, and instead we call BN code from OpenSSL
     - Zlib is now external, in a library
     - The make-ssh-known-hosts script is no longer included
     - TSS has been removed
     - MD5 is now external, in the OpenSSL library
     - RC4 support has been replaced with ARC4 support from OpenSSL
     - Blowfish is now external, in the OpenSSL library

    [The licence continues]

    Note that any information and cryptographic algorithms used in this
    software are publicly available on the Internet and at any major
    bookstore, scientific library, and patent office worldwide.  More
    information can be found e.g. at "http://www.cs.hut.fi/crypto".

    The legal status of this program is some combination of all these
    permissions and restrictions.  Use only at your own responsibility.
    You will be responsible for any legal consequences yourself; I am not
    making any claims whether possessing or using this is legal or not in
    your country, and I am not taking any responsibility on your behalf.


			    NO WARRANTY

    BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
    FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
    PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
    OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
    MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
    TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
    PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
    REPAIR OR CORRECTION.

    IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
    REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
    INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
    OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
    TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
    YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
    PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
    POSSIBILITY OF SUCH DAMAGES.

To All Licensees, Distributors of Any Version of BSD:

As you know, certain of the Berkeley Software Distribution ("BSD") source code files require that further distributions of products containing all or portions of the software, acknowledge within their advertising materials that such products contain software developed by UC Berkeley and its contributors.

Specifically, the provision reads:

"     * 3. All advertising materials mentioning features or use of this software
      *	   must display the following acknowledgement:
      *	   This product includes software developed by the University of
      *	   California, Berkeley and its contributors."

Effective immediately, licensees and distributors are no longer required to include the acknowledgement within advertising materials. Accordingly, the foregoing paragraph of those BSD Unix files containing it is hereby deleted in its entirety.
