Jed offers the entire applicable GNU gettext spec'd set of
functions, but also offers some nicer wrappers around them.
The api for gettext was written for a language with no function
overloading, so Jed allows a little more of that.
Many thanks to Joshua I. Miller - unrtst@cpan.org - who wrote
gettext.js back in 2008. I was able to vet a lot of my ideas
against his. I also made sure Jed passed against his tests
in order to offer easy upgrades -- jsgettext.berlios.de

// Big Integer Library v. 5.5
// Created 2000, last modified 2013
// Leemon Baird
// www.leemon.com
//
// Version history:
// v 5.5 17 Mar 2013
// - two lines of a form like "if (x<0) x+=n" had the "if" changed to "while" to
// handle the case when x<-n. (Thanks to James Ansell for finding that bug)
// v 5.4 3 Oct 2009
// - added "var i" to greaterShift() so i is not global. (Thanks to Péter Szabó for finding that bug)
//
// v 5.3 21 Sep 2009
// - added randProbPrime(k) for probable primes
// - unrolled loop in mont_ (slightly faster)
// - millerRabin now takes a bigInt parameter rather than an int
//
// v 5.2 15 Sep 2009
// - fixed capitalization in call to int2bigInt in randBigInt
// (thanks to Emili Evripidou, Reinhold Behringer, and Samuel Macaleese for finding that bug)
//
// v 5.1 8 Oct 2007
// - renamed inverseModInt_ to inverseModInt since it doesn't change its parameters
// - added functions GCD and randBigInt, which call GCD_ and randBigInt_
// - fixed a bug found by Rob Visser (see comment with his name below)
// - improved comments
//
// This file is public domain. You can use it for any purpose without restriction.
// I do not guarantee that it is correct, so use it at your own risk. If you use
// it for something interesting, I'd appreciate hearing about it. If you find
// any bugs or make any improvements, I'd appreciate hearing about those too.
// It would also be nice if my name and URL were left in the comments. But none
// of that is required.
//
// This code defines a bigInt library for arbitrary-precision integers.
// A bigInt is an array of integers storing the value in chunks of bpe bits,
// little endian (buff[0] is the least significant word).
// Negative bigInts are stored two's complement. Almost all the functions treat
// bigInts as nonnegative. The few that view them as two's complement say so
// in their comments. Some functions assume their parameters have at least one
// leading zero element. Functions with an underscore at the end of the name put
// their answer into one of the arrays passed in, and have unpredictable behavior
// in case of overflow, so the caller must make sure the arrays are big enough to
// hold the answer. But the average user should never have to call any of the
// underscored functions. Each important underscored function has a wrapper function
// of the same name without the underscore that takes care of the details for you.
// For each underscored function where a parameter is modified, that same variable
// must not be used as another argument too. So, you cannot square x by doing
// multMod_(x,x,n). You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
// Or simply use the multMod(x,x,n) function without the underscore, where
// such issues never arise, because non-underscored functions never change
// their parameters; they always allocate new memory for the answer that is returned.
//
// These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
// For most functions, if it needs a BigInt as a local variable it will actually use
// a global, and will only allocate to it only when it's not the right size. This ensures
// that when a function is called repeatedly with same-sized parameters, it only allocates
// memory on the first call.
//
// Note that for cryptographic purposes, the calls to Math.random() must
// be replaced with calls to a better pseudorandom number generator.
//
// In the following, "bigInt" means a bigInt with at least one leading zero element,
// and "integer" means a nonnegative integer less than radix. In some cases, integer
// can be negative. Negative bigInts are 2s complement.
//
// The following functions do not modify their inputs.
// Those returning a bigInt, string, or Array will dynamically allocate memory for that value.
// Those returning a boolean will return the integer 0 (false) or 1 (true).
// Those returning boolean or int will not allocate memory except possibly on the first
// time they're called with a given parameter size.
//
// bigInt add(x,y) //return (x+y) for bigInts x and y.
// bigInt addInt(x,n) //return (x+n) where x is a bigInt and n is an integer.
// string bigInt2str(x,base) //return a string form of bigInt x in a given base, with 2 <= base <= 95
// int bitSize(x) //return how many bits long the bigInt x is, not counting leading zeros
// bigInt dup(x) //return a copy of bigInt x
// boolean equals(x,y) //is the bigInt x equal to the bigint y?

// int inverseModInt(x,n) //return x**(-1) mod n, for integers x and n. Return 0 if there is no inverse
// boolean isZero(x) //is the bigInt x equal to zero?
// boolean millerRabin(x,b) //does one round of Miller-Rabin base integer b say that bigInt x is possibly prime? (b is bigInt, 1<b<x)
// boolean millerRabinInt(x,b) //does one round of Miller-Rabin base integer b say that bigInt x is possibly prime? (b is int, 1<b<x)
// bigInt mod(x,n) //return a new bigInt equal to (x mod n) for bigInts x and n.
// int modInt(x,n) //return x mod n for bigInt x and integer n.
// bigInt mult(x,y) //return x*y for bigInts x and y. This is faster when y<x.
// bigInt multMod(x,y,n) //return (x*y mod n) for bigInts x,y,n. For greater speed, let y<x.
// boolean negative(x) //is bigInt x negative?
// bigInt powMod(x,y,n) //return (x**y mod n) where x,y,n are bigInts and ** is exponentiation. 0**0=1. Faster for odd n.
// bigInt randBigInt(n,s) //return an n-bit random BigInt (n>=1). If s=1, then the most significant of those n bits is set to 1.
// bigInt randTruePrime(k) //return a new, random, k-bit, true prime bigInt using Maurer's algorithm.
// bigInt randProbPrime(k) //return a new, random, k-bit, probable prime bigInt (probability it's composite less than 2^-80).
// bigInt str2bigInt(s,b,n,m) //return a bigInt for number represented in string s in base b with at least n bits and m array elements
// bigInt sub(x,y) //return (x-y) for bigInts x and y. Negative answers will be 2s complement
// bigInt trim(x,k) //return a copy of x with exactly k leading zero elements

// The following functions are based on algorithms from the _Handbook of Applied Cryptography_
// powMod_() = algorithm 14.94, Montgomery exponentiation
// eGCD_,inverseMod_() = algorithm 14.61, Binary extended GCD_
// GCD_() = algorothm 14.57, Lehmer's algorithm
// mont_() = algorithm 14.36, Montgomery multiplication
// divide_() = algorithm 14.20 Multiple-precision division
// squareMod_() = algorithm 14.16 Multiple-precision squaring
// randTruePrime_() = algorithm 4.62, Maurer's algorithm
// millerRabin() = algorithm 4.24, Miller-Rabin algorithm
//
// Profiling shows:
// randTruePrime_() spends:
// 10% of its time in calls to powMod_()
// 85% of its time in calls to millerRabin()
// millerRabin() spends:
// 99% of its time in calls to powMod_() (always with a base of 2)
// powMod_() spends:
// 94% of its time in calls to mont_() (almost always with x==y)
//
// This suggests there are several ways to speed up this library slightly:
// - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
// -- this should especially focus on being fast when raising 2 to a power mod n
// - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test
// - tune the parameters in randTruePrime_(), including c, m, and recLimit
// - speed up the single loop in mont_() that takes 95% of the runtime, perhaps by reducing checking
// within the loop when all the parameters are the same length.
//
// There are several ideas that look like they wouldn't help much at all:
// - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
// - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
// - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
// followed by a Montgomery reduction. The intermediate answer will be twice as long as x, so that
// method would be slower. This is unfortunate because the code currently spends almost all of its time
// doing mont_(x,x,...), both for randTruePrime_() and powMod_(). A faster method for Montgomery squaring
// would have a large impact on the speed of randTruePrime_() and powMod_(). HAC has a couple of poorly-worded
// sentences that seem to imply it's faster to do a non-modular square followed by a single
// Montgomery reduction, but that's obviously wrong.

* > $iq({to: 'you', from: 'me', type: 'get', id: '1'})

* to an XMPP server and dispatches events to the user callbacks as
* data arrives. It supports SASL PLAIN, SASL DIGEST-MD5, SASL SCRAM-SHA1
* and legacy authentication.
*
* After creating a Strophe.Connection object, the user will typically
* call connect() with a user supplied callback to handle connection level
* events like authentication failure, disconnection, or connection
* complete.
*
* The user will also have several event handlers defined by using
* addHandler() and addTimedHandler(). These will allow the user code to
* respond to interesting stanzas or do something periodically with the
* connection. These handlers will be active once authentication is
* finished.
*
* To send data to the connection, use send().

/** Constructor: Strophe.Connection
* Create and initialize a Strophe.Connection object.
*
* The transport-protocol for this connection will be chosen automatically
* based on the given service parameter. URLs starting with "ws://" or
* "wss://" will use WebSockets, URLs starting with "http://", "https://"
* or without a protocol will use BOSH.
*
* To make Strophe connect to the current host you can leave out the protocol
* and host part and just pass the path, e.g.
*
* > var conn = new Strophe.Connection("/http-bind/");
*
* WebSocket options:
*
* If you want to connect to the current host with a WebSocket connection you
* can tell Strophe to use WebSockets through a "protocol" attribute in the
* optional options parameter. Valid values are "ws" for WebSocket and "wss"
* for Secure WebSocket.
* So to connect to "wss://CURRENT_HOSTNAME/xmpp-websocket" you would call
*
* > var conn = new Strophe.Connection("/xmpp-websocket/", {protocol: "wss"});
*
* Note that relative URLs _NOT_ starting with a "/" will also include the path
* of the current site.
*
* Also because downgrading security is not permitted by browsers, when using
* relative URLs both BOSH and WebSocket connections will use their secure
* variants if the current connection to the site is also secure (https).
*
* BOSH options:
*
* by adding "sync" to the options, you can control if requests will
* be made synchronously or not. The default behaviour is asynchronous.
* If you want to make requests synchronous, make "sync" evaluate to true:
* > var conn = new Strophe.Connection("/http-bind/", {sync: true});
* You can also toggle this on an already established connection:
* > conn.options.sync = true;
*
*
* Parameters:
* (String) service - The BOSH or WebSocket service URL.
* (Object) options - A hash of configuration options
*
* Returns:
* A new Strophe.Connection object.

*
* As a convenience, the ns parameters applies to the top level element

* matching /iq/query elements easy.
*
* The options argument contains handler matching flags that affect how
* matches are determined. Currently the only flag is matchBare (a
* boolean). When matchBare is true, the from parameter and the from
* attribute on the stanza will be matched as bare JIDs instead of
* full JIDs. To use this, pass {matchBare: true} as the value of
* options. The default value for matchBare is false.

* Parameters:

* (String) ns - The namespace to match.
* (String) name - The stanza name to match.
* (String) type - The stanza type attribute to match.
* (String) id - The stanza id attribute to match.
