-\modulesynopsis{Interface to the GNU MP library for arbitrary
-precision arithmetic.}
-
-
-\deprecated{2.2}{See the references at the end of this section for
- information about packages which provide similar
- functionality. This module will be removed in Python
- 2.3.}
-
-
-This is an optional module. It is only available when Python is
-configured to include it, which requires that the GNU MP software is
-installed.
-\index{MP, GNU library}
-\index{arbitrary precision integers}
-\index{integer!arbitrary precision}
-
-This module implements the interface to part of the GNU MP library,
-which defines arbitrary precision integer and rational number
-arithmetic routines. Only the interfaces to the \emph{integer}
-(\function{mpz_*()}) routines are provided. If not stated
-otherwise, the description in the GNU MP documentation can be applied.
-
-Support for rational numbers\index{rational numbers} can be
-implemented in Python. For an example, see the
-\module{Rat}\withsubitem{(demo module)}{\ttindex{Rat}} module, provided as
-\file{Demos/classes/Rat.py} in the Python source distribution.
-
-In general, \dfn{mpz}-numbers can be used just like other standard
-Python numbers, e.g., you can use the built-in operators like \code{+},
-\code{*}, etc., as well as the standard built-in functions like
-\function{abs()}, \function{int()}, \ldots, \function{divmod()},
-\function{pow()}. \strong{Please note:} the \emph{bitwise-xor}
-operation has been implemented as a bunch of \emph{and}s,
-\emph{invert}s and \emph{or}s, because the library lacks an
-\cfunction{mpz_xor()} function, and I didn't need one.
-
-You create an mpz-number by calling the function \function{mpz()} (see
-below for an exact description). An mpz-number is printed like this:
-\code{mpz(\var{value})}.
-
-
-\begin{funcdesc}{mpz}{value}
- Create a new mpz-number. \var{value} can be an integer, a long,
- another mpz-number, or even a string. If it is a string, it is
- interpreted as an array of radix-256 digits, least significant digit
- first, resulting in a positive number. See also the \method{binary()}
- method, described below.
-\end{funcdesc}
-
-\begin{datadesc}{MPZType}
- The type of the objects returned by \function{mpz()} and most other
- functions in this module.
-\end{datadesc}
-
-
-A number of \emph{extra} functions are defined in this module. Non
-mpz-arguments are converted to mpz-values first, and the functions
-return mpz-numbers.
-
-\begin{funcdesc}{powm}{base, exponent, modulus}
- Return \code{pow(\var{base}, \var{exponent}) \%{} \var{modulus}}. If
- \code{\var{exponent} == 0}, return \code{mpz(1)}. In contrast to the
- \C{} library function, this version can handle negative exponents.
-\end{funcdesc}
-
-\begin{funcdesc}{gcd}{op1, op2}
- Return the greatest common divisor of \var{op1} and \var{op2}.
-\end{funcdesc}
-
-\begin{funcdesc}{gcdext}{a, b}
- Return a tuple \code{(\var{g}, \var{s}, \var{t})}, such that
- \code{\var{a}*\var{s} + \var{b}*\var{t} == \var{g} == gcd(\var{a}, \var{b})}.
-\end{funcdesc}
-
-\begin{funcdesc}{sqrt}{op}
- Return the square root of \var{op}. The result is rounded towards zero.
-\end{funcdesc}
-
-\begin{funcdesc}{sqrtrem}{op}
- Return a tuple \code{(\var{root}, \var{remainder})}, such that
- \code{\var{root}*\var{root} + \var{remainder} == \var{op}}.
-\end{funcdesc}
-
-\begin{funcdesc}{divm}{numerator, denominator, modulus}
- Returns a number \var{q} such that
- \code{\var{q} * \var{denominator} \%{} \var{modulus} ==
- \var{numerator}}. One could also implement this function in Python,
- using \function{gcdext()}.
-\end{funcdesc}
-
-An mpz-number has one method:
-
-\begin{methoddesc}[mpz]{binary}{}
- Convert this mpz-number to a binary string, where the number has been
- stored as an array of radix-256 digits, least significant digit first.
-
- The mpz-number must have a value greater than or equal to zero,
- otherwise \exception{ValueError} will be raised.

-\section{\module{rotor} ---
- Enigma-like encryption and decryption}
-
-\declaremodule{builtin}{rotor}
-\modulesynopsis{Enigma-like encryption and decryption.}
-
-\deprecated{2.3}{The encryption algorithm is insecure.}
-
-
-This module implements a rotor-based encryption algorithm, contributed by
-Lance Ellinghouse\index{Ellinghouse, Lance}. The design is derived
-from the Enigma device\indexii{Enigma}{device}, a machine
-used during World War II to encipher messages. A rotor is simply a
-permutation. For example, if the character `A' is the origin of the rotor,
-then a given rotor might map `A' to `L', `B' to `Z', `C' to `G', and so on.
-To encrypt, we choose several different rotors, and set the origins of the
-rotors to known positions; their initial position is the ciphering key. To
-encipher a character, we permute the original character by the first rotor,
-and then apply the second rotor's permutation to the result. We continue
-until we've applied all the rotors; the resulting character is our
-ciphertext. We then change the origin of the final rotor by one position,
-from `A' to `B'; if the final rotor has made a complete revolution, then we
-rotate the next-to-last rotor by one position, and apply the same procedure
-recursively. In other words, after enciphering one character, we advance
-the rotors in the same fashion as a car's odometer. Decoding works in the
-same way, except we reverse the permutations and apply them in the opposite
-order.
-\indexii{Enigma}{cipher}
-
-The available functions in this module are:
-
-\begin{funcdesc}{newrotor}{key\optional{, numrotors}}
-Return a rotor object. \var{key} is a string containing the encryption key
-for the object; it can contain arbitrary binary data but not null bytes.
-The key will be used
-to randomly generate the rotor permutations and their initial positions.
-\var{numrotors} is the number of rotor permutations in the returned object;
-if it is omitted, a default value of 6 will be used.
-\end{funcdesc}
-
-Rotor objects have the following methods:
-
-\begin{methoddesc}[rotor]{setkey}{key}
-Sets the rotor's key to \var{key}. The key should not contain null bytes.
-\end{methoddesc}
-
-\begin{methoddesc}[rotor]{encrypt}{plaintext}
-Reset the rotor object to its initial state and encrypt \var{plaintext},
-returning a string containing the ciphertext. The ciphertext is always the
-same length as the original plaintext.
-\end{methoddesc}
-
-\begin{methoddesc}[rotor]{encryptmore}{plaintext}
-Encrypt \var{plaintext} without resetting the rotor object, and return a
-string containing the ciphertext.
-\end{methoddesc}
-
-\begin{methoddesc}[rotor]{decrypt}{ciphertext}
-Reset the rotor object to its initial state and decrypt \var{ciphertext},
-returning a string containing the plaintext. The plaintext string will
-always be the same length as the ciphertext.
-\end{methoddesc}
-
-\begin{methoddesc}[rotor]{decryptmore}{ciphertext}
-Decrypt \var{ciphertext} without resetting the rotor object, and return a
-string containing the plaintext.
-\end{methoddesc}
-
-An example usage:
-\begin{verbatim}
->>> import rotor
->>> rt = rotor.newrotor('key', 12)
->>> rt.encrypt('bar')
-'\xab4\xf3'
->>> rt.encryptmore('bar')
-'\xef\xfd$'
->>> rt.encrypt('bar')
-'\xab4\xf3'
->>> rt.decrypt('\xab4\xf3')
-'bar'
->>> rt.decryptmore('\xef\xfd$')
-'bar'
->>> rt.decrypt('\xef\xfd$')
-'l(\xcd'
->>> del rt
-\end{verbatim}
-
-The module's code is not an exact simulation of the original Enigma
-device; it implements the rotor encryption scheme differently from the
-original. The most important difference is that in the original
-Enigma, there were only 5 or 6 different rotors in existence, and they
-were applied twice to each character; the cipher key was the order in
-which they were placed in the machine. The Python \module{rotor}
-module uses the supplied key to initialize a random number generator;
-the rotor permutations and their initial positions are then randomly
-generated. The original device only enciphered the letters of the
-alphabet, while this module can handle any 8-bit binary data; it also
-produces binary output. This module can also operate with an
-arbitrary number of rotors.
-
-The original Enigma cipher was broken in 1944. % XXX: Is this right?
-The version implemented here is probably a good deal more difficult to crack
-(especially if you use many rotors), but it won't be impossible for
-a truly skillful and determined attacker to break the cipher. So if you want
-to keep the NSA out of your files, this rotor cipher may well be unsafe, but
-for discouraging casual snooping through your files, it will probably be
-just fine, and may be somewhat safer than using the \UNIX{} \program{crypt}
-command.

- Efficient iteration over a file}

-\declaremodule{extension}{xreadlines}
-\modulesynopsis{Efficient iteration over the lines of a file.}
-
-\versionadded{2.1}
-
-\deprecated{2.3}{Use \samp{for \var{line} in \var{file}} instead.}
-
-This module defines a new object type which can efficiently iterate
-over the lines of a file. An xreadlines object is a sequence type
-which implements simple in-order indexing beginning at \code{0}, as
-required by \keyword{for} statement or the
-\function{filter()} function.
-
-Thus, the code
-
-\begin{verbatim}
-import xreadlines, sys
-
-for line in xreadlines.xreadlines(sys.stdin):
- pass
-\end{verbatim}
-
-has approximately the same speed and memory consumption as
-
-\begin{verbatim}
-while 1:
- lines = sys.stdin.readlines(8*1024)
- if not lines: break
- for line in lines:
- pass
-\end{verbatim}
-
-except the clarity of the \keyword{for} statement is retained in the
-former case.
-
-\begin{funcdesc}{xreadlines}{fileobj}
- Return a new xreadlines object which will iterate over the contents
- of \var{fileobj}. \var{fileobj} must have a \method{readlines()}
- method that supports the \var{sizehint} parameter. \note{Because
- the \method{readlines()} method buffers data, this effectively
- ignores the effects of setting the file object as unbuffered.}
-\end{funcdesc}
-
-An xreadlines object \var{s} supports the following sequence
-operation:
-
-\begin{tableii}{c|l}{code}{Operation}{Result}
- \lineii{\var{s}[\var{i}]}{\var{i}'th line of \var{s}}
-\end{tableii}
-
-If successive values of \var{i} are not sequential starting from
-\code{0}, this code will raise \exception{RuntimeError}.
-
-After the last line of the file is read, this code will raise an
-\exception{IndexError}.
