-COPYING POLICY AND OTHER LEGAL ISSUES
-
-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".
-
-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.
-
-[ RSA is no longer included. ]
-[ IDEA is no longer included. ]
-[ DES is now external. ]
-[ GMP is now external. No more GNU licence. ]
-[ Zlib is now external. ]
-[ The make-ssh-known-hosts script is no longer included. ]
-[ TSS has been removed. ]
-[ MD5 is now external. ]
-[ RC4 support has been removed. ]
-[ Blowfish is now external. ]
-
-The 32-bit CRC implementation in crc32.c is due to Gary S. Brown.
-Comments in the file indicate it may be used for any purpose without
-restrictions.
-
-The 32-bit CRC compensation attack detector in deattack.c was
-contributed by CORE SDI S.A. under a BSD-style license. See
-http://www.core-sdi.com/english/ssh/ for details.
-
-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

-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE

-howto:
-	1) generate server key:
-		$ ssh-keygen -d -f /etc/ssh_host_dsa_key -N ''
-	2) enable ssh2:
-		server: add 'Protocol 2,1' to /etc/sshd_config
-		client: ssh -o 'Protocol 2,1', or add to .ssh/config
-	3) DSA authentication similar to RSA (add keys to ~/.ssh/authorized_keys2)
-	   interop w/ ssh.com dsa-keys:
-		ssh-keygen -f /key/from/ssh.com -X >> ~/.ssh/authorized_keys2
-	   and vice versa
-		ssh-keygen -f /privatekey/from/openssh -x > ~/.ssh2/mykey.pub
-		echo Key mykey.pub >> ~/.ssh2/authorization
-
-works:
-	secsh-transport: works w/o rekey
-		proposal exchange, i.e. different enc/mac/comp per direction
-		encryption: blowfish-cbc, 3des-cbc, arcfour, cast128-cbc
-		mac: hmac-md5, hmac-sha1, (hmac-ripemd160)
-		compression: zlib, none
-	secsh-userauth: passwd and pubkey with DSA
-	secsh-connection: pty+shell or command, flow control works (window adjust)
-		tcp-forwarding: -L works, -R incomplete
-		x11-fwd
-	dss/dsa: host key database in ~/.ssh/known_hosts2
-	client interops w/ sshd2, lshd
-	server interops w/ ssh2, lsh, ssh.com's Windows client, SecureCRT, F-Secure SSH Client 4.0, SecureFX (secure ftp)
-	server supports multiple concurrent sessions (e.g. with SSH.com Windows client)
-todo:
-	re-keying
-	secsh-connection features:
-		 tcp-forwarding, agent-fwd
-	auth other than passwd, and DSA-pubkey:
-		 keyboard-interactive, (PGP-pubkey?)
-	config
-	server-auth w/ old host-keys
-	cleanup
-	advanced key storage?
-	keynote
-	sftp

- * This file defines five types of data structures: singly-linked lists, 
- * lists, simple queues, tail queues, and circular queues.
- *
- *
- * A singly-linked list is headed by a single forward pointer. The elements
- * are singly linked for minimum space and pointer manipulation overhead at
- * the expense of O(n) removal for arbitrary elements. New elements can be
- * added to the list after an existing element or at the head of the list.
- * Elements being removed from the head of the list should use the explicit
- * macro for this purpose for optimum efficiency. A singly-linked list may
- * only be traversed in the forward direction.  Singly-linked lists are ideal
- * for applications with large datasets and few or no removals or for
- * implementing a LIFO queue.
- *
- * A list is headed by a single forward pointer (or an array of forward
- * pointers for a hash table header). The elements are doubly linked
- * so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before
- * or after an existing element or at the head of the list. A list
- * may only be traversed in the forward direction.
- *
- * A simple queue is headed by a pair of pointers, one the head of the
- * list and the other to the tail of the list. The elements are singly
- * linked to save space, so elements can only be removed from the
- * head of the list. New elements can be added to the list before or after
- * an existing element, at the head of the list, or at the end of the
- * list. A simple queue may only be traversed in the forward direction.
- *
- * A tail queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or
- * after an existing element, at the head of the list, or at the end of
- * the list. A tail queue may be traversed in either direction.
- *
- * A circle queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or after
- * an existing element, at the head of the list, or at the end of the list.
- * A circle queue may be traversed in either direction, but has a more
- * complex end of list detection.
- *
- * For details on the use of these macros, see the queue(3) manual page.

- * This file defines data structures for different types of trees:
- * splay trees and red-black trees.
- *
- * A splay tree is a self-organizing data structure.  Every operation
- * on the tree causes a splay to happen.  The splay moves the requested
- * node to the root of the tree and partly rebalances it.
- *
- * This has the benefit that request locality causes faster lookups as
- * the requested nodes move to the top of the tree.  On the other hand,
- * every lookup causes memory writes.
- *
- * The Balance Theorem bounds the total access time for m operations
- * and n inserts on an initially empty tree as O((m + n)lg n).  The
- * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
- *
- * A red-black tree is a binary search tree with the node color as an
- * extra attribute.  It fulfills a set of conditions:
- *	- every search path from the root to a leaf consists of the
- *	  same number of black nodes,
- *	- each red node (except for the root) has a black parent,
- *	- each leaf node is black.
- *
- * Every operation on a red-black tree is bounded as O(lg n).
- * The maximum height of a red-black tree is 2lg (n+1).
