+aproba
+======
+
+A ridiculously light-weight function argument validator
+
+```
+var validate = require("aproba")
+
+function myfunc(a, b, c) {
+  // `a` must be a string, `b` a number, `c` a function
+  validate('SNF', arguments) // [a,b,c] is also valid
+}
+
+myfunc('test', 23, function () {}) // ok
+myfunc(123, 23, function () {}) // type error
+myfunc('test', 23) // missing arg error
+myfunc('test', 23, function () {}, true) // too many args error
+
+```
+
+Valid types are:
+
+| type | description
+| :--: | :----------
+| *    | matches any type
+| A    | `Array.isArray` OR an `arguments` object
+| S    | typeof == string
+| N    | typeof == number
+| F    | typeof == function
+| O    | typeof == object and not type A and not type E
+| B    | typeof == boolean
+| E    | `instanceof Error` OR `null` **(special: see below)**
+| Z    | == `null`
+
+Validation failures throw one of three exception types, distinguished by a
+`code` property of `EMISSINGARG`, `EINVALIDTYPE` or `ETOOMANYARGS`.
+
+If you pass in an invalid type then it will throw with a code of
+`EUNKNOWNTYPE`.
+
+If an **error** argument is found and is not null then the remaining
+arguments are optional.  That is, if you say `ESO` then that's like using a
+non-magical `E` in: `E|ESO|ZSO`.
+
+### But I have optional arguments?!
+
+You can provide more than one signature by separating them with pipes `|`.
+If any signature matches the arguments then they'll be considered valid.
+
+So for example, say you wanted to write a signature for
+`fs.createWriteStream`.  The docs for it describe it thusly:
+
+```
+fs.createWriteStream(path[, options])
+```
+
+This would be a signature of `SO|S`.  That is, a string and and object, or
+just a string.
+
+Now, if you read the full `fs` docs, you'll see that actually path can ALSO
+be a buffer.  And options can be a string, that is:
+```
+path <String> | <Buffer>
+options <String> | <Object>
+```
+
+To reproduce this you have to fully enumerate all of the possible
+combinations and that implies a signature of `SO|SS|OO|OS|S|O`.  The
+awkwardness is a feature: It reminds you of the complexity you're adding to
+your API when you do this sort of thing.
+
+
+### Browser support
+
+This has no dependencies and should work in browsers, though you'll have
+noisier stack traces.
+
+### Why this exists
+
+I wanted a very simple argument validator. It needed to do two things:
+
+1. Be more concise and easier to use than assertions
+
+2. Not encourage an infinite bikeshed of DSLs
+
+This is why types are specified by a single character and there's no such
+thing as an optional argument. 
+
+This is not intended to validate user data. This is specifically about
+asserting the interface of your functions.
+
+If you need greater validation, I encourage you to write them by hand or
+look elsewhere.

+Hi, figured we could actually use a changelog now:
+
+## 1.1.4 2017-04-21
+
+* Fix typo in package.json
+
+## 1.1.3 2017-04-21
+
+* Improve documentation and limit files included in the distribution.
+
+## 1.1.2 2016-03-15
+
+* Add tracker group cycle detection and tests for it
+
+## 1.1.1 2016-01-29
+
+* Fix a typo in stream completion tracker
+
+## 1.1.0 2016-01-29
+
+* Rewrote completion percent computation to be low impact– no more walking a
+  tree of completion groups every time we need this info.  Previously, with
+  medium sized tree of completion groups, even a relatively modest number of
+  calls to the top level `completed()` method would result in absurd numbers
+  of calls overall as it walked down the tree. We now, instead, keep track as
+  we bubble up changes, so the computation is limited to when data changes and
+  to the depth of that one branch, instead of _every_ node. (Plus, we were already
+  incurring _this_ cost, since we already bubbled out changes.)
+* Moved different tracker types out to their own files.
+* Made tests test for TOO MANY events too.
+* Standarized the source code formatting

+are-we-there-yet
+----------------
+
+Track complex hiearchies of asynchronous task completion statuses.  This is
+intended to give you a way of recording and reporting the progress of the big
+recursive fan-out and gather type workflows that are so common in async.
+
+What you do with this completion data is up to you, but the most common use case is to
+feed it to one of the many progress bar modules.
+
+Most progress bar modules include a rudamentary version of this, but my
+needs were more complex.
+
+Usage
+=====
+
+```javascript
+var TrackerGroup = require("are-we-there-yet").TrackerGroup
+
+var top = new TrackerGroup("program")
+
+var single = top.newItem("one thing", 100)
+single.completeWork(20)
+
+console.log(top.completed()) // 0.2
+
+fs.stat("file", function(er, stat) {
+  if (er) throw er  
+  var stream = top.newStream("file", stat.size)
+  console.log(top.completed()) // now 0.1 as single is 50% of the job and is 20% complete
+                              // and 50% * 20% == 10%
+  fs.createReadStream("file").pipe(stream).on("data", function (chunk) {
+    // do stuff with chunk
+  })
+  top.on("change", function (name) {
+    // called each time a chunk is read from "file"
+    // top.completed() will start at 0.1 and fill up to 0.6 as the file is read
+  })
+})
+```
+
+Shared Methods
+==============
+
+* var completed = tracker.completed()
+
+Implemented in: `Tracker`, `TrackerGroup`, `TrackerStream`
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1.
+
+* tracker.finish()
+
+Implemented in: `Tracker`, `TrackerGroup`
+
+Marks the tracker as completed. With a TrackerGroup this marks all of its
+components as completed.
+
+Marks all of the components of this tracker as finished, which in turn means
+that `tracker.completed()` for this will now be 1.
+
+This will result in one or more `change` events being emitted.
+
+Events
+======
+
+All tracker objects emit `change` events with the following arguments:
+
+```
+function (name, completed, tracker)
+```
+
+`name` is the name of the tracker that originally emitted the event,
+or if it didn't have one, the first containing tracker group that had one.
+
+`completed` is the percent complete (as returned by `tracker.completed()` method).
+
+`tracker` is the tracker object that you are listening for events on.
+
+TrackerGroup
+============
+
+* var tracker = new TrackerGroup(**name**)
+
+  * **name** *(optional)* - The name of this tracker group, used in change
+    notifications if the component updating didn't have a name. Defaults to undefined.
+
+Creates a new empty tracker aggregation group. These are trackers whose
+completion status is determined by the completion status of other trackers.
+
+* tracker.addUnit(**otherTracker**, **weight**)
+
+  * **otherTracker** - Any of the other are-we-there-yet tracker objects
+  * **weight** *(optional)* - The weight to give the tracker, defaults to 1.
+
+Adds the **otherTracker** to this aggregation group. The weight determines
+how long you expect this tracker to take to complete in proportion to other
+units.  So for instance, if you add one tracker with a weight of 1 and
+another with a weight of 2, you're saying the second will take twice as long
+to complete as the first.  As such, the first will account for 33% of the
+completion of this tracker and the second will account for the other 67%.
+
+Returns **otherTracker**.
+
+* var subGroup = tracker.newGroup(**name**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subGroup = tracker.addUnit(new TrackerGroup(name), weight)
+```
+
+* var subItem = tracker.newItem(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subItem = tracker.addUnit(new Tracker(name, todo), weight)
+```
+
+* var subStream = tracker.newStream(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subStream = tracker.addUnit(new TrackerStream(name, todo), weight)
+```
+
+* console.log( tracker.debug() )
+
+Returns a tree showing the completion of this tracker group and all of its
+children, including recursively entering all of the children.
+
+Tracker
+=======
+
+* var tracker = new Tracker(**name**, **todo**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **todo** *(optional)* The amount of work todo (a number). Defaults to 0.
+
+Ordinarily these are constructed as a part of a tracker group (via
+`newItem`).
+
+* var completed = tracker.completed()
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1. If
+total work to be done is 0 then it will return 0.
+
+* tracker.addWork(**todo**)
+
+  * **todo** A number to add to the amount of work to be done.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.
+
+* tracker.completeWork(**completed**)
+
+  * **completed** A number to add to the work complete
+
+Increase the amount of work complete, thus increasing the completion percentage.
+Will never increase the work completed past the amount of work todo. That is,
+percentages > 100% are not allowed. Triggers a `change` event.
+
+* tracker.finish()
+
+Marks this tracker as finished, tracker.completed() will now be 1. Triggers
+a `change` event.
+
+TrackerStream
+=============
+
+* var tracker = new TrackerStream(**name**, **size**, **options**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **size** *(optional)* The number of bytes being sent through this stream.
+  * **options** *(optional)* A hash of stream options
+
+The tracker stream object is a pass through stream that updates an internal
+tracker object each time a block passes through.  It's intended to track
+downloads, file extraction and other related activities. You use it by piping
+your data source into it and then using it as your data source.
+
+If your data has a length attribute then that's used as the amount of work
+completed when the chunk is passed through.  If it does not (eg, object
+streams) then each chunk counts as completing 1 unit of work, so your size
+should be the total number of objects being streamed.
+
+* tracker.addWork(**todo**)
+
+  * **todo** Increase the expected overall size by **todo** bytes.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.

This is\nintended to give you a way of recording and reporting the progress of the big\nrecursive fan-out and gather type workflows that are so common in async.\n\nWhat you do with this completion data is up to you, but the most common use case is to\nfeed it to one of the many progress bar modules.\n\nMost progress bar modules include a rudamentary version of this, but my\nneeds were more complex.\n\nUsage\n=====\n\n```javascript\nvar TrackerGroup = require(\"are-we-there-yet\").TrackerGroup\n\nvar top = new TrackerGroup(\"program\")\n\nvar single = top.newItem(\"one thing\", 100)\nsingle.completeWork(20)\n\nconsole.log(top.completed()) // 0.2\n\nfs.stat(\"file\", function(er, stat) {\n  if (er) throw er  \n  var stream = top.newStream(\"file\", stat.size)\n  console.log(top.completed()) // now 0.1 as single is 50% of the job and is 20% complete\n                              // and 50% * 20% == 10%\n  fs.createReadStream(\"file\").pipe(stream).on(\"data\", function (chunk) {\n    // do stuff with chunk\n  })\n  top.on(\"change\", function (name) {\n    // called each time a chunk is read from \"file\"\n    // top.completed() will start at 0.1 and fill up to 0.6 as the file is read\n  })\n})\n```\n\nShared Methods\n==============\n\n* var completed = tracker.completed()\n\nImplemented in: `Tracker`, `TrackerGroup`, `TrackerStream`\n\nReturns the ratio of completed work to work to be done. Range of 0 to 1.\n\n* tracker.finish()\n\nImplemented in: `Tracker`, `TrackerGroup`\n\nMarks the tracker as completed. With a TrackerGroup this marks all of its\ncomponents as completed.\n\nMarks all of the components of this tracker as finished, which in turn means\nthat `tracker.completed()` for this will now be 1.\n\nThis will result in one or more `change` events being emitted.\n\nEvents\n======\n\nAll tracker objects emit `change` events with the following arguments:\n\n```\nfunction (name, completed, tracker)\n```\n\n`name` is the name of the tracker that originally emitted the event,\nor if it didn't have one, the first containing tracker group that had one.\n\n`completed` is the percent complete (as returned by `tracker.completed()` method).\n\n`tracker` is the tracker object that you are listening for events on.\n\nTrackerGroup\n============\n\n* var tracker = new TrackerGroup(**name**)\n\n  * **name** *(optional)* - The name of this tracker group, used in change\n    notifications if the component updating didn't have a name. Defaults to undefined.\n\nCreates a new empty tracker aggregation group. These are trackers whose\ncompletion status is determined by the completion status of other trackers.\n\n* tracker.addUnit(**otherTracker**, **weight**)\n\n  * **otherTracker** - Any of the other are-we-there-yet tracker objects\n  * **weight** *(optional)* - The weight to give the tracker, defaults to 1.\n\nAdds the **otherTracker** to this aggregation group. The weight determines\nhow long you expect this tracker to take to complete in proportion to other\nunits.  So for instance, if you add one tracker with a weight of 1 and\nanother with a weight of 2, you're saying the second will take twice as long\nto complete as the first.  As such, the first will account for 33% of the\ncompletion of this tracker and the second will account for the other 67%.\n\nReturns **otherTracker**.\n\n* var subGroup = tracker.newGroup(**name**, **weight**)\n\nThe above is exactly equivalent to:\n\n```javascript\n  var subGroup = tracker.addUnit(new TrackerGroup(name), weight)\n```\n\n* var subItem = tracker.newItem(**name**, **todo**, **weight**)\n\nThe above is exactly equivalent to:\n\n```javascript\n  var subItem = tracker.addUnit(new Tracker(name, todo), weight)\n```\n\n* var subStream = tracker.newStream(**name**, **todo**, **weight**)\n\nThe above is exactly equivalent to:\n\n```javascript\n  var subStream = tracker.addUnit(new TrackerStream(name, todo), weight)\n```\n\n* console.log( tracker.debug() )\n\nReturns a tree showing the completion of this tracker group and all of its\nchildren, including recursively entering all of the children.\n\nTracker\n=======\n\n* var tracker = new Tracker(**name**, **todo**)\n\n  * **name** *(optional)* The name of this counter to report in change\n    events.  Defaults to undefined.\n  * **todo** *(optional)* The amount of work todo (a number). Defaults to 0.\n\nOrdinarily these are constructed as a part of a tracker group (via\n`newItem`).\n\n* var completed = tracker.completed()\n\nReturns the ratio of completed work to work to be done. Range of 0 to 1. If\ntotal work to be done is 0 then it will return 0.\n\n* tracker.addWork(**todo**)\n\n  * **todo** A number to add to the amount of work to be done.\n\nIncreases the amount of work to be done, thus decreasing the completion\npercentage.  Triggers a `change` event.\n\n* tracker.completeWork(**completed**)\n\n  * **completed** A number to add to the work complete\n\nIncrease the amount of work complete, thus increasing the completion percentage.\nWill never increase the work completed past the amount of work todo. That is,\npercentages > 100% are not allowed. Triggers a `change` event.\n\n* tracker.finish()\n\nMarks this tracker as finished, tracker.completed() will now be 1. Triggers\na `change` event.\n\nTrackerStream\n=============\n\n* var tracker = new TrackerStream(**name**, **size**, **options**)\n\n  * **name** *(optional)* The name of this counter to report in change\n    events.  Defaults to undefined.\n  * **size** *(optional)* The number of bytes being sent through this stream.\n  * **options** *(optional)* A hash of stream options\n\nThe tracker stream object is a pass through stream that updates an internal\ntracker object each time a block passes through.  It's intended to track\ndownloads, file extraction and other related activities. You use it by piping\nyour data source into it and then using it as your data source.\n\nIf your data has a length attribute then that's used as the amount of work\ncompleted when the chunk is passed through.  If it does not (eg, object\nstreams) then each chunk counts as completing 1 unit of work, so your size\nshould be the total number of objects being streamed.\n\n* tracker.addWork(**todo**)\n\n  * **todo** Increase the expected overall size by **todo** bytes.\n\nIncreases the amount of work to be done, thus decreasing the completion\npercentage.  Triggers a `change` event.\n",

+# assert
+
+[![Build Status](https://travis-ci.org/defunctzombie/commonjs-assert.svg?branch=master)](https://travis-ci.org/defunctzombie/commonjs-assert)
+
+This module is used for writing unit tests for your applications, you can access it with require('assert').
+
+The API is derived from the [commonjs 1.0 unit testing](http://wiki.commonjs.org/wiki/Unit_Testing/1.0) spec and the [node.js assert module](http://nodejs.org/api/assert.html)
+
+## assert.fail(actual, expected, message, operator)
+Throws an exception that displays the values for actual and expected separated by the provided operator.
+
+## assert(value, message), assert.ok(value, [message])
+Tests if value is truthy, it is equivalent to assert.equal(true, !!value, message);
+
+## assert.equal(actual, expected, [message])
+Tests shallow, coercive equality with the equal comparison operator ( == ).
+
+## assert.notEqual(actual, expected, [message])
+Tests shallow, coercive non-equality with the not equal comparison operator ( != ).
+
+## assert.deepEqual(actual, expected, [message])
+Tests for deep equality.
+
+## assert.notDeepEqual(actual, expected, [message])
+Tests for any deep inequality.
+
+## assert.strictEqual(actual, expected, [message])
+Tests strict equality, as determined by the strict equality operator ( === )
+
+## assert.notStrictEqual(actual, expected, [message])
+Tests strict non-equality, as determined by the strict not equal operator ( !== )
+
+## assert.throws(block, [error], [message])
+Expects block to throw an error. error can be constructor, regexp or validation function.
+
+Validate instanceof using constructor:
+
+```javascript
+assert.throws(function() { throw new Error("Wrong value"); }, Error);
+```
+
+Validate error message using RegExp:
+
+```javascript
+assert.throws(function() { throw new Error("Wrong value"); }, /value/);
+```
+
+Custom error validation:
+
+```javascript
+assert.throws(function() {
+    throw new Error("Wrong value");
+}, function(err) {
+    if ( (err instanceof Error) && /value/.test(err) ) {
+        return true;
+    }
+}, "unexpected error");
+```
+
+## assert.doesNotThrow(block, [message])
+Expects block not to throw an error, see assert.throws for details.
+
+## assert.ifError(value)
+Tests if value is not a false value, throws if it is a true value. Useful when testing the first argument, error in callbacks.

Useful when testing the first argument, error in callbacks.\n",

+node-bindings
+=============
+### Helper module for loading your native module's .node file
+
+This is a helper module for authors of Node.js native addon modules.
+It is basically the "swiss army knife" of `require()`ing your native module's
+`.node` file.
+
+Throughout the course of Node's native addon history, addons have ended up being
+compiled in a variety of different places, depending on which build tool and which
+version of node was used. To make matters worse, now the _gyp_ build tool can
+produce either a _Release_ or _Debug_ build, each being built into different
+locations.
+
+This module checks _all_ the possible locations that a native addon would be built
+at, and returns the first one that loads successfully.
+
+
+Installation
+------------
+
+Install with `npm`:
+
+``` bash
+$ npm install bindings
+```
+
+Or add it to the `"dependencies"` section of your _package.json_ file.
+
+
+Example
+-------
+
+`require()`ing the proper bindings file for the current node version, platform
+and architecture is as simple as:
+
+``` js
+var bindings = require('bindings')('binding.node')
+
+// Use your bindings defined in your C files
+bindings.your_c_function()
+```
+
+
+Nice Error Output
+-----------------
+
+When the `.node` file could not be loaded, `node-bindings` throws an Error with
+a nice error message telling you exactly what was tried. You can also check the
+`err.tries` Array property.
+
+```
+Error: Could not load the bindings file. Tried:
+ → /Users/nrajlich/ref/build/binding.node
+ → /Users/nrajlich/ref/build/Debug/binding.node
+ → /Users/nrajlich/ref/build/Release/binding.node
+ → /Users/nrajlich/ref/out/Debug/binding.node

+ → /Users/nrajlich/ref/Release/binding.node
+ → /Users/nrajlich/ref/build/default/binding.node
+ → /Users/nrajlich/ref/compiled/0.8.2/darwin/x64/binding.node
+    at bindings (/Users/nrajlich/ref/node_modules/bindings/bindings.js:84:13)
+    at Object.<anonymous> (/Users/nrajlich/ref/lib/ref.js:5:47)
+    at Module._compile (module.js:449:26)

+    at Module.load (module.js:356:32)
+    at Function.Module._load (module.js:312:12)
+    ...
+```
+
+The searching for the `.node` file will originate from the first directory in which has a `package.json` file is found.

To make matters worse, now the _gyp_ build tool can\nproduce either a _Release_ or _Debug_ build, each being built into different\nlocations.\n\nThis module checks _all_ the possible locations that a native addon would be built\nat, and returns the first one that loads successfully.\n\n\nInstallation\n------------\n\nInstall with `npm`:\n\n``` bash\n$ npm install bindings\n```\n\nOr add it to the `\"dependencies\"` section of your _package.json_ file.\n\n\nExample\n-------\n\n`require()`ing the proper bindings file for the current node version, platform\nand architecture is as simple as:\n\n``` js\nvar bindings = require('bindings')('binding.node')\n\n// Use your bindings defined in your C files\nbindings.your_c_function()\n```\n\n\nNice Error Output\n-----------------\n\nWhen the `.node` file could not be loaded, `node-bindings` throws an Error with\na nice error message telling you exactly what was tried. You can also check the\n`err.tries` Array property.\n\n```\nError: Could not load the bindings file. Tried:\n → /Users/nrajlich/ref/build/binding.node\n → /Users/nrajlich/ref/build/Debug/binding.node\n → /Users/nrajlich/ref/build/Release/binding.node\n → /Users/nrajlich/ref/out/Debug/binding.node\n → /Users/nrajlich/ref/Debug/binding.node\n → /Users/nrajlich/ref/out/Release/binding.node\n → /Users/nrajlich/ref/Release/binding.node\n → /Users/nrajlich/ref/build/default/binding.node\n → /Users/nrajlich/ref/compiled/0.8.2/darwin/x64/binding.node\n    at bindings (/Users/nrajlich/ref/node_modules/bindings/bindings.js:84:13)\n    at Object.<anonymous> (/Users/nrajlich/ref/lib/ref.js:5:47)\n    at Module._compile (module.js:449:26)\n    at Object.Module._extensions..js (module.js:467:10)\n    at Module.load (module.js:356:32)\n    at Function.Module._load (module.js:312:12)\n    ...\n```\n\nThe searching for the `.node` file will originate from the first directory in which has a `package.json` file is found. \n\nLicense\n-------\n\n(The MIT License)\n\nCopyright (c) 2012 Nathan Rajlich &lt;nathan@tootallnate.net&gt;\n\nPermission is hereby granted, free of charge, to any person obtaining\na copy of this software and associated documentation files (the\n'Software'), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to\npermit persons to whom the Software is furnished to do so, subject to\nthe following conditions:\n\nThe above copyright notice and this permission notice shall be\nincluded in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND,\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\nIN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY\nCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,\nTORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE\nSOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.\n",

+When `.end()` or `.flush()` is called, it'll pad the block with zeroes.

+# Console Control Strings
+
+A library of cross-platform tested terminal/console command strings for
+doing things like color and cursor positioning.  This is a subset of both
+ansi and vt100.  All control codes included work on both Windows & Unix-like
+OSes, except where noted.
+
+## Usage
+
+```js
+var consoleControl = require('console-control-strings')
+
+console.log(consoleControl.color('blue','bgRed', 'bold') + 'hi there' + consoleControl.color('reset'))
+process.stdout.write(consoleControl.goto(75, 10))
+```
+
+## Why Another?
+
+There are tons of libraries similar to this one.  I wanted one that was:
+
+1. Very clear about compatibility goals.
+2. Could emit, for instance, a start color code without an end one.
+3. Returned strings w/o writing to streams.
+4. Was not weighed down with other unrelated baggage.
+
+## Functions
+
+### var code = consoleControl.up(_num = 1_)
+
+Returns the escape sequence to move _num_ lines up.
+
+### var code = consoleControl.down(_num = 1_)
+
+Returns the escape sequence to move _num_ lines down.
+
+### var code = consoleControl.forward(_num = 1_)
+
+Returns the escape sequence to move _num_ lines righ.
+
+### var code = consoleControl.back(_num = 1_)
+
+Returns the escape sequence to move _num_ lines left.
+
+### var code = consoleControl.nextLine(_num = 1_)
+
+Returns the escape sequence to move _num_ lines down and to the beginning of
+the line.
+
+### var code = consoleControl.previousLine(_num = 1_)
+
+Returns the escape sequence to move _num_ lines up and to the beginning of
+the line.
+
+### var code = consoleControl.eraseData()
+
+Returns the escape sequence to erase everything from the current cursor
+position to the bottom right of the screen.  This is line based, so it
+erases the remainder of the current line and all following lines.
+
+### var code = consoleControl.eraseLine()
+
+Returns the escape sequence to erase to the end of the current line.
+
+### var code = consoleControl.goto(_x_, _y_)
+
+Returns the escape sequence to move the cursor to the designated position. 
+Note that the origin is _1, 1_ not _0, 0_.
+
+### var code = consoleControl.gotoSOL()
+
+Returns the escape sequence to move the cursor to the beginning of the
+current line. (That is, it returns a carriage return, `\r`.)
+
+### var code = consoleControl.beep()
+
+Returns the escape sequence to cause the termianl to beep.  (That is, it
+returns unicode character `\x0007`, a Control-G.)
+
+### var code = consoleControl.hideCursor()
+
+Returns the escape sequence to hide the cursor.
+
+### var code = consoleControl.showCursor()
+
+Returns the escape sequence to show the cursor.
+
+### var code = consoleControl.color(_colors = []_)
+
+### var code = consoleControl.color(_color1_, _color2_, _…_, _colorn_)
+
+Returns the escape sequence to set the current terminal display attributes
+(mostly colors).  Arguments can either be a list of attributes or an array
+of attributes.  The difference between passing in an array or list of colors
+and calling `.color` separately for each one, is that in the former case a
+single escape sequence will be produced where as in the latter each change
+will have its own distinct escape sequence.  Each attribute can be one of:
+
+* Reset:
+  * **reset** – Reset all attributes to the terminal default.
+* Styles:
+  * **bold** – Display text as bold.  In some terminals this means using a
+    bold font, in others this means changing the color.  In some it means
+    both.
+  * **italic** – Display text as italic. This is not available in most Windows terminals.
+  * **underline** – Underline text. This is not available in most Windows Terminals.
+  * **inverse** – Invert the foreground and background colors.
+  * **stopBold** – Do not display text as bold.
+  * **stopItalic** – Do not display text as italic.
+  * **stopUnderline** – Do not underline text.
+  * **stopInverse** – Do not invert foreground and background.
+* Colors:
+  * **white**
+  * **black**
+  * **blue**
+  * **cyan**
+  * **green**
+  * **magenta**
+  * **red**
+  * **yellow**
+  * **grey** / **brightBlack**
+  * **brightRed**
+  * **brightGreen**
+  * **brightYellow**
+  * **brightBlue**
+  * **brightMagenta**
+  * **brightCyan**
+  * **brightWhite**
+* Background Colors:
+  * **bgWhite**
+  * **bgBlack**
+  * **bgBlue**
+  * **bgCyan**
+  * **bgGreen**
+  * **bgMagenta**
+  * **bgRed**
+  * **bgYellow**
+  * **bgGrey** / **bgBrightBlack**
+  * **bgBrightRed**
+  * **bgBrightGreen**
+  * **bgBrightYellow**
+  * **bgBrightBlue**
+  * **bgBrightMagenta**
+  * **bgBrightCyan**
+  * **bgBrightWhite**

+node-ffi
+========
+### Node.js Foreign Function Interface
+[![Build Status](https://travis-ci.org/node-ffi/node-ffi.svg?branch=master)](https://travis-ci.org/node-ffi/node-ffi)
+[![Build Status](https://ci.appveyor.com/api/projects/status/n81apam1igfw8491?svg=true)](https://ci.appveyor.com/project/TooTallNate/node-ffi)
+
+`node-ffi` is a Node.js addon for loading and calling dynamic libraries using
+pure JavaScript. It can be used to create bindings to native libraries without
+writing any C++ code.
+
+It also simplifies the augmentation of node.js with C code as it takes care of
+handling the translation of types across JavaScript and C, which can add reams
+of boilerplate code to your otherwise simple C. See the `example/factorial`
+for an example of this use case.
+
+**WARNING**: node-ffi assumes you know what you're doing. You can pretty easily
+create situations where you will segfault the interpreter and unless you've got
+C debugger skills, you probably won't know what's going on.
+
+Example
+-------
+
+``` js
+var ffi = require('ffi');
+
+var libm = ffi.Library('libm', {
+  'ceil': [ 'double', [ 'double' ] ]
+});
+libm.ceil(1.5); // 2
+
+// You can also access just functions in the current process by passing a null
+var current = ffi.Library(null, {
+  'atoi': [ 'int', [ 'string' ] ]
+});
+current.atoi('1234'); // 1234
+```
+
+For a more detailed introduction, see the [node-ffi tutorial page][tutorial].
+
+Requirements
+------------
+
+ * Linux, OS X, Windows, or Solaris.
+ * `libffi` comes bundled with node-ffi; it does *not* need to be installed on your system.
+ * The current version is tested to run on node v0.6, v0.8, v0.9 and v0.10.
+
+Installation
+------------
+
+Make sure you've installed all the [necessary build
+tools](https://github.com/TooTallNate/node-gyp#installation) for your platform,
+then invoke:
+
+``` bash
+$ npm install ffi
+```
+
+Source Install / Manual Compilation
+-----------------------------------
+
+To compile from source it's easiest to use
+[`node-gyp`](https://github.com/TooTallNate/node-gyp):
+
+``` bash
+$ npm install -g node-gyp
+```
+
+Now you can compile `node-ffi`:
+
+``` bash
+$ git clone git://github.com/node-ffi/node-ffi.git
+$ cd node-ffi
+$ node-gyp rebuild
+```
+
+Types
+-----
+
+The types that you specify in function declarations correspond to ref's types
+system. So [see its docs][ref-types] for
+a reference if you are unfamiliar.
+
+V8 and 64-bit Types
+-------------------
+
+Internally, V8 stores integers that will fit into a 32-bit space in a 32-bit
+integer, and those that fall outside of this get put into double-precision
+floating point numbers. This is problematic because FP numbers are imprecise.
+To get around this, the methods in node-ffi that deal with 64-bit integers return
+strings and can accept strings as parameters.
+
+Call Overhead
+-------------
+
+There is non-trivial overhead associated with FFI calls. Comparing a hard-coded
+binding version of `strtoul()` to an FFI version of `strtoul()` shows that the
+native hard-coded binding is orders of magnitude faster. So don't just use the
+C version of a function just because it's faster. There's a significant cost in
+FFI calls, so make them worth it.
