13     * As far as I am concerned, the code I have written for this software
14     * can be used freely for any purpose.  Any derived versions of this
15     * software must be clearly marked as such, and if the derived work is
16     * incompatible with the protocol description in the RFC file, it must be
17     * called by a name other than "ssh" or "Secure Shell".

20     *  However, I am not implying to give any licenses to any patents or
21     * copyrights held by third parties, and the software includes parts that
22     * are not under my direct control.  As far as I know, all included
23     * source code is used in accordance with the relevant license agreements
24     * and can be used freely for any purpose (the GNU license being the most
25     * restrictive); see below for details.
26
27    [However, none of that term is relevant at this point in time.  All of
28    these restrictively licenced software components which he talks about
29    have been removed from OpenSSH, ie.
30
31     - RSA is no longer included, found in the OpenSSL library
32     - IDEA is no longer included, it's use is depricated
33     - DES is now external, in the OpenSSL library
34     - GMP is no longer used, and instead we call BN code from OpenSSL
35     - Zlib is now external, in a library
36     - The make-ssh-known-hosts script is no longer included
37     - TSS has been removed
38     - MD5 is now external, in the OpenSSL library
39     - RC4 support has been replaced with ARC4 support from OpenSSL
40     - Blowfish is now external, in the OpenSSL library
