-In order for two parties to exchange M-209 messages, each must set up their
-device in exactly the same manner. This was accomplished by publishing key
-lists in code books which were distributed to end users. A code book instructed
-users on what key list to use on any given day in a given month.  Each key list
-detailed the numerous wheel pin and lug settings that needed to be made for
-a given day. Because there are so many settings, the ``m209`` utility allows
-users to store key lists in a key file for convenience. So let us first create
-a key file that hold 30 key lists::
+Contents:
 
-   $ m209 keygen -n 30
-
-This command randomly creates 30 key lists and stores them in a file called
-``m209keys.cfg`` by default. We did not specify a starting key list indicator, so
-30 random ones were chosen. The first 13 lines of our new key file are
-displayed below::
-
-   $ head -n 13 m209keys.cfg 
-   [AB]
-   lugs = 0-4*4 0-5*6 1-0*10 2-0*2 3-0 3-5*2 3-6 4-5
-   wheel1 = BDFGIKRSTUWX
-   wheel2 = BCEJKLORSUX
-   wheel3 = CFHJKLMQSTU
-   wheel4 = ABCDHIJMOPRTU
-   wheel5 = BCEFINPS
-   wheel6 = ACDEHJN
-   check = GZWUU SFYQN NFAKK FXSEN FAFMF B
-
-   [AK]
-   lugs = 0-4*2 0-5*9 0-6 1-0*3 1-2 1-5 1-6*2 3-0*8
-   wheel1 = ABDEFHIJMQSUXZ
-
-.. NOTE:: 
-   If you are following along at home, you'll probably get different
-   output than what is shown here. This is because the key lists are generated
-   at random, and it is very unlikely that your key list matches mine!
-
-Here we can see that the first key list in our file has the indicator ``AB``
-(shown in square brackets), and we can see the settings for the lugs and six
-wheels. The notation is explained later. Also included is a so-called check
-string. Because there are so many settings, it is quite error-prone to set up
-an M-209. This check string allows the operator to verify their work.  After
-configuring the M-209 with the given settings, the operator can set the six key
-wheels to ``AAAAAA``, then encipher the letter ``A`` 26 times. If the message
-that appears on the paper tape matches the check string, the operator knows the
-machine is set up correctly for the day.
-
-After the key list ``AB``, the key list ``AK`` starts, and so on for all 30 key
-lists.
-
-Now that we have created a key file, we can encrypt our first message. The
-``m209`` utility has many options to let you have fine control over the various
-encryption parameters. These are explained in detail later. If you omit these
-parameters they are simply chosen at random. Here is the simplest example of
-encryping a message::
-
-   $ m209 encrypt -t "THE PIZZA HAS ARRIVED STOP NO SIGN OF ENEMY FORCES STOP"
-   IIPDU FHLMB LASGD KTLDO OSRMZ PWGEB HYMCB IKSPT IUEPF FUHEO NQTWI VTDPC GSPQX IIPDU FHLMB
-
-What just happened here? Since we did not specify a key file, the default
-``m209keys.cfg`` was used. Since we did not specify a key list indicator, one
-was chosen randomly from the key file. Other encryption parameters, explained
-later, were also randomly chosen. Next, the message given on the command-line
-was encrypted using the standard US Army procedure described in the references.
-This resulted in the encrypted message, which is displayed in 5-letter groups.
-Notice that the first and last 2 groups are identical. These are special
-indicators that tell the receiver how to decrypt the message. In particular
-note that the last 2 letters in the second and last groups are ``MB``. This is
-the key list indicator and tells the receiver what key list was used. The
-remaining groups in the middle make up the encrypted message.
-
-Astute M-209 enthusiasts will note that our message included spaces. Actual
-M-209 units only allow the input of the letters ``A`` through ``Z``. Whenever
-a space was needed, the operator inserted the letter ``Z``. The ``m209``
-utility automatically performs this substitution for convenience.
-
-Let's suppose our message was then sent to our recipient, either by courier,
-Morse code over radio, or in the modern age, email or even Twitter. In order
-for our receiver to decrypt our message they must also have the identical key
-list named ``MB``. We will assume for now that our key file, ``m209keys.cfg``
-was sent to our receiver earlier in some secure manner. The receiver then
-issues this command::
-
-   $ m209 decrypt -t "IIPDU FHLMB LASGD KTLDO OSRMZ PWGEB HYMCB IKSPT IUEPF FUHEO NQTWI VTDPC GSPQX IIPDU FHLMB"
-   THE PI  A HAS ARRIVED STOP NO SIGN OF ENEMY FORCES STOP
-
-Here again, since no key file was explicitly specified, the file
-``m209keys.cfg`` was used. The file was searched for the key list ``MB``. Then
-the standard Army procedure was followed, making use of the indicator groups to
-decrypt the message, which is displayed as output.
-
-But wait, what happened to our Pizza? Why are the ``Z``'s missing? This is how
-an actual M-209 operates. Recall that an operator must substitute a letter
-``Z`` whenever a space is needed. The M-209 helpfully replaces the letter ``Z``
-in the decrypt output with a space as an aid to the operator. As a side effect,
-legitimate uses of the letter ``Z`` are blanked out. But usually it is clear
-from context what has happened, and the operator has to put them back into the
-message before passing it up the chain of command.
-
-It may also happen that the original message did not fit perfectly into an even
-number of 5-letter groups. In that case the encrypted message would be padded
-with ``X`` characters according to procedure. Upon decrypt, these ``X``
-characters would appear as garbage characters on the end of the message. The
-receiving operator would simply ignore these letters. Note that our message did
-not exhibit this behavior.
-
-This is all you need to know to start creating your own M-209 messages! For
-more details, consult the command-line ``m209`` documentation.

-Library Tutorial
-----------------
-
-Here is one way to perform the encrypt and decrypt operations from the
-command-line tutorial, above. In order to produce the same output, we explicity
-specify the encryption parameters: the key list, the external message
-indicator, and the system indicator. These parameters are explained in the
-reference documentation.
-
-.. literalinclude:: ../examples/encrypt.py
-
-This program outputs::
-
-   IIPDU FHLMB LASGD KTLDO OSRMZ PWGEB HYMCB IKSPT IUEPF FUHEO NQTWI VTDPC GSPQX IIPDU FHLMB
-
-A decrypt is just a bit more complicated. After constructing a ``StdProcedure``
-object, you hand it the encrypted message to analyze. The procedure object
-examines the groups in the message and extracts all the indicators. These are
-returned as a ``DecryptParams`` named tuple which indicates, amongst other
-things, what key list is required. It is then up to you to obtain this key list
-somehow. Here we use the ``read_key_list()`` function to do so. After
-installing the key list into the procedure object, you can finally call
-``decrypt()``:
-
-.. literalinclude:: ../examples/decrypt.py
-
-This program prints::
