-through2-map
-============
-
-[![NPM](https://nodei.co/npm/through2-map.png)](https://nodei.co/npm/through2-map/)
-
-This is a super thin wrapper around [through2](http://npm.im/through2) that works like `Array.prototype.map` but for streams.
-
-For when through2 is just too verbose :wink:
-
-Note you will **NOT** be able to skip chunks. This is intended for modification only. If you want filter the stream content, use either `through2` or `through2-filter`. This transform also does not have a `flush` function.
-
-**IMPORTANT:** If you return `null` from your function, the stream will end there.
-
-```js
-
-var map = require("through2-map")
-
-var truncate = map(function (chunk) {
-  return chunk.slice(0, 10)
-})
-
-// vs. with through2:
-var truncate = through2(function (chunk, encoding, callback) {
-  this.push(chunk.slice(0, 10))
-  return callback()
-})
-
-// Then use your map:
-source.pipe(truncate).pipe(sink)
-
-// Additionally accepts `wantStrings` argument to conver buffers into strings
-var stripTags = map({wantStrings: true}, function (str) {
-  // OMG don't actually use this
-  return str.replace(/<.*?>/g, "")
-})
-
-// Works like `Array.prototype.map` meaning you can specify a function that
-// takes up to two* arguments: fn(chunk, index)
-var spaceout = map({wantStrings: true}, function (chunk, index) {
-  return (index % 2 == 0) ? chunk + "\n\n" : chunk
-})
-
-// vs. with through2:
-var spaceout = through2(function (chunk, encoding, callback) {
-  if (this.index == undefined) this.index = 0
-  var buf = (this.index++ % 2 == 0) ? Buffer.concat(chunk, new Buffer("\n\n")) : chunk
-  this.push(buf)
-  return callback()
-})
-
-```
-
-*Differences from `Array.prototype.map`:
-  * Cannot insert `null` elements into the stream without aborting.
-  * No third `array` callback argument. That would require realizing the entire stream, which is generally counter-productive to stream operations.
-  * `Array.prototype.map` doesn't modify the source Array, which is somewhat nonsensical when applied to streams.
-
-API
----
-
-`require("through2-map")([options,] fn)`
----
-
-Create a `stream.Transform` instance that will call `fn(chunk, index)` on each stream segment.
-
-`var Tx = require("through2-map").ctor([options,] fn)`
----
-
-Create a reusable `stream.Transform` TYPE that can be called via `new Tx` or `Tx()` to create an instance.
-
-`require("through2-map").obj([options,] fn)`
----
-
-Create a `through2-map` instance that defaults to `objectMode: true`.
-
-`require("through2-map").objCtor([options,] fn)`
----
-
-Just like ctor, but with `objectMode: true` defaulting to true.
-
-Options
--------
-
-  * wantStrings: Automatically call chunk.toString() for the super lazy.
-  * all other through2 options

-API
-===
-
-`terminus([options,] _writeFunction)`
----
-
-Create a `streams.Writable` instance that will call `_writeFunction` on every chunk. Consult the [stream.Writable](http://nodejs.org/api/stream.html#stream_class_stream_writable_1) documentation for instructions on creating a `_write` function.
-
-`terminus.ctor([options,] _writeFunction)`
----
-
-Create a `streams.Writable` Subclass that can be used to re-create stream.Writable instances with the same _writeFunction.
-
-`terminus.devnull([options])`
----
-
-Create a `stream.Writable` instance that is akin to writing to `dev/null` i.e. it doesn't do anything except give your stream somewhere to go.
-
-Why? Because if your pipeline doesn't terminate on a Writable stream, it will get paused at the High Water Mark with nothing to unpause it. I've most often seen this when people are using PassThrough streams, or Transforms that incorporate all required behavior.
-
-`terminus.concat([options], fn)`
----
-
-Collect the entire stream and when it is done, call `fn(contents)`. This is similar to the stream behavior of [concat-stream](http://npm.im/concat-stream) without the extra Array/Buffer concat behavior and entirely in streams2.
-
-`terminus.tail([options], fn)`
----
-
-A slightly less complicated version of `terminus([options,] _writeFunction)` that only requries you to provide a function that operates as `fn(chunk, encoding)`.
-
-options
----
-
-All functions accept standard `streams.Writable` options, that is:
-
-  * highWaterMark `[Number]` Buffer level when write() starts returning false. `Default=16kb`
-  * decodeStrings `[Boolean]` Whether not to decode strings into Buffers before passing them to _write() `Default=true`
-  * objectMode `[Boolean]` If the content is Javascript objects versus strings/buffers. `Default=false`
-
-objectMode
----
-
-The most common option you'll be setting is `objectMode` which will enable you to stream Javascript objects, e.g. records. Unfortunately this is currently required and **ALL** streams2 parts of your stream pipeline must be in `objectMode` or you'll get errors. It's annoying, I know.

-
-This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
-
-If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
-
-**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
-
-**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-Browser-friendly inheritance fully compatible with standard node.js
-[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
-
-This package exports standard `inherits` from node.js `util` module in
-node environment, but also provides alternative browser-friendly
-implementation through [browser
-field](https://gist.github.com/shtylman/4339901). Alternative
-implementation is a literal copy of standard one located in standalone
-module to avoid requiring of `util`. It also has a shim for old
-browsers with no `Object.create` support.
-
-While keeping you sure you are using standard `inherits`
-implementation in node.js environment, it allows bundlers such as
-[browserify](https://github.com/substack/node-browserify) to not
-include full `util` package to your client code if all you need is
-just `inherits` function. It worth, because browser shim for `util`
-package is large and `inherits` is often the single function you need
-from it.
-
-It's recommended to use this package instead of
-`require('util').inherits` for any code that has chances to be used
-not only in node.js but in browser too.
-
-## usage
-
-```js
-var inherits = require('inherits');
-// then use exactly as the standard one
-```
-
-## note on version ~1.0
-
-Version ~1.0 had completely different motivation and is not compatible
-neither with 2.0 nor with standard node.js `inherits`.
-
-If you are using version ~1.0 and planning to switch to ~2.0, be
-careful:
-
-* new version uses `super_` instead of `super` for referencing
-  superclass
-* new version overwrites current prototype while old one preserves any
-  existing fields on it

-Extend like a boss
-
-xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
-
-## Examples
-
-```js
-var extend = require("xtend")
-
-// extend returns a new object. Does not mutate arguments
-var combination = extend({
-    a: "a",
-    b: 'c'
-}, {
-    b: "b"
-})
-// { a: "a", b: "b" }
-```

-**A tiny wrapper around Node streams.Transform (Streams2) to avoid explicit subclassing noise**
-
-Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
-
-Note: A **Streams3** version of through2 is available in npm with the tag `"1.0"` rather than `"latest"` so an `npm install through2` will get you the current Streams2 version (version number is 0.x.x). To use a Streams3 version use `npm install through2@1` to fetch the latest version 1.x.x. More information about Streams2 vs Streams3 and recommendations [here](http://www.nearform.com/nodecrunch/dont-use-nodes-core-stream-module).
-
-```js
-fs.createReadStream('ex.txt')
-  .pipe(through2(function (chunk, enc, callback) {
-
-    for (var i = 0; i < chunk.length; i++)
-      if (chunk[i] == 97)
-        chunk[i] = 122 // swap 'a' for 'z'
-
-    this.push(chunk)
-
-    callback()
-
-   }))
-  .pipe(fs.createWriteStream('out.txt'))
-```
-
-Or object streams:

-```js
-var all = []
-
-fs.createReadStream('data.csv')
-  .pipe(csv2())
-  .pipe(through2.obj(function (chunk, enc, callback) {
-
-    var data = {
-        name    : chunk[0]
-      , address : chunk[3]
-      , phone   : chunk[10]
-    }
-
-    this.push(data)
-
-    callback()
-
-  }))
-  .on('data', function (data) {
-    all.push(data)
-  })
-  .on('end', function () {
-    doSomethingSpecial(all)
-  })
-```
-
-Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
-
-## API
-
-<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
-
-Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
-
-### options
-
-The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
-
-The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2({ objectMode: true, allowHalfOpen: false }, function (chunk, enc, cb) {
-
-    this.push(new Buffer('wut?'))
-    cb()
-
-  })
-  .pipe(fs.createWriteStream('/tmp/wut.txt'))
-```
-
-### transformFunction
-
-The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
-
-To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
-
-If you **do not provide a `transformFunction`** then you will get a simple simple pass-through stream.
-
-### flushFunction
-
-The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
-
-<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
-
-Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
-
-```js
-var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
-  if (record.temp != null && record.unit = "F") {
-    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
-    record.unit = "C"
-  }
-  this.push(record)
-  callback()
-})
-
-// Create instances of FToC like so:
-var converter = new FToC()
-// Or:
-var converter = FToC()
-// Or specify/override options when you instantiate, if you prefer:
-var converter = FToC({objectMode: true})
-```

-This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
-
-If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
-
-**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
-
-**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

-
-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-Browser-friendly inheritance fully compatible with standard node.js
-[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
-
-This package exports standard `inherits` from node.js `util` module in
-node environment, but also provides alternative browser-friendly
-implementation through [browser
-field](https://gist.github.com/shtylman/4339901). Alternative
-implementation is a literal copy of standard one located in standalone
-module to avoid requiring of `util`. It also has a shim for old
-browsers with no `Object.create` support.
-
-While keeping you sure you are using standard `inherits`
-implementation in node.js environment, it allows bundlers such as
-[browserify](https://github.com/substack/node-browserify) to not
-include full `util` package to your client code if all you need is
-just `inherits` function. It worth, because browser shim for `util`
-package is large and `inherits` is often the single function you need
-from it.
-
-It's recommended to use this package instead of
-`require('util').inherits` for any code that has chances to be used
-not only in node.js but in browser too.
-
-## usage
-
-```js
-var inherits = require('inherits');
-// then use exactly as the standard one
-```
-
-## note on version ~1.0
-
-Version ~1.0 had completely different motivation and is not compatible
-neither with 2.0 nor with standard node.js `inherits`.
-
-If you are using version ~1.0 and planning to switch to ~2.0, be
-careful:
-
-* new version uses `super_` instead of `super` for referencing
-  superclass
-* new version overwrites current prototype while old one preserves any
-  existing fields on it

-Extend like a boss
-
-xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes presedence.
-
-## Examples
-
-```js
-var extend = require("xtend")
-
-// extend returns a new object. Does not mutate arguments
-var combination = extend({
-    a: "a"
-}, {
-    b: "b"
-})
-// { a: "a", b: "b" }
-```
