+# fast-levenshtein - Levenshtein algorithm in Javascript
+
+[![Build Status](https://secure.travis-ci.org/hiddentao/fast-levenshtein.png)](http://travis-ci.org/hiddentao/fast-levenshtein)
+[![NPM module](https://badge.fury.io/js/fast-levenshtein.png)](https://badge.fury.io/js/fast-levenshtein)
+[![NPM downloads](https://img.shields.io/npm/dm/fast-levenshtein.svg?maxAge=2592000)](https://www.npmjs.com/package/fast-levenshtein)
+[![Follow on Twitter](https://img.shields.io/twitter/url/http/shields.io.svg?style=social&label=Follow&maxAge=2592000)](https://twitter.com/hiddentao)
+
+An efficient Javascript implementation of the [Levenshtein algorithm](http://en.wikipedia.org/wiki/Levenshtein_distance) with locale-specific collator support.
+
+## Features
+
+* Works in node.js and in the browser.
+* Better performance than other implementations by not needing to store the whole matrix ([more info](http://www.codeproject.com/Articles/13525/Fast-memory-efficient-Levenshtein-algorithm)).
+* Locale-sensitive string comparisions if needed.
+* Comprehensive test suite and performance benchmark.
+* Small: <1 KB minified and gzipped
+
+## Installation
+
+### node.js
+
+Install using [npm](http://npmjs.org/):
+
+```bash
+$ npm install fast-levenshtein
+```
+
+### Browser
+
+Using bower:
+
+```bash
+$ bower install fast-levenshtein
+```
+
+If you are not using any module loader system then the API will then be accessible via the `window.Levenshtein` object.
+
+## Examples
+
+**Default usage**
+
+```javascript
+var levenshtein = require('fast-levenshtein');
+
+var distance = levenshtein.get('back', 'book');   // 2
+var distance = levenshtein.get('我愛你', '我叫你');   // 1
+```
+
+**Locale-sensitive string comparisons**
+
+It supports using [Intl.Collator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Collator) for locale-sensitive  string comparisons:
+
+```javascript
+var levenshtein = require('fast-levenshtein');
+
+levenshtein.get('mikailovitch', 'Mikhaïlovitch', { useCollator: true});
+// 1
+```
+
+## Building and Testing
+
+To build the code and run the tests:
+
+```bash
+$ npm install -g grunt-cli
+$ npm install
+$ npm run build
+```
+
+## Performance
+
+_Thanks to [Titus Wormer](https://github.com/wooorm) for [encouraging me](https://github.com/hiddentao/fast-levenshtein/issues/1) to do this._
+
+Benchmarked against other node.js levenshtein distance modules (on Macbook Air 2012, Core i7, 8GB RAM):
+
+```bash
+Running suite Implementation comparison [benchmark/speed.js]...
+>> levenshtein-edit-distance x 234 ops/sec ±3.02% (73 runs sampled)
+>> levenshtein-component x 422 ops/sec ±4.38% (83 runs sampled)
+>> levenshtein-deltas x 283 ops/sec ±3.83% (78 runs sampled)
+>> natural x 255 ops/sec ±0.76% (88 runs sampled)
+>> levenshtein x 180 ops/sec ±3.55% (86 runs sampled)
+>> fast-levenshtein x 1,792 ops/sec ±2.72% (95 runs sampled)
+Benchmark done.
+Fastest test is fast-levenshtein at 4.2x faster than levenshtein-component
+```
+
+You can run this benchmark yourself by doing:
+
+```bash
+$ npm install
+$ npm run build
+$ npm run benchmark
+```
+

+# json-stable-stringify
+
+deterministic version of `JSON.stringify()` so you can get a consistent hash
+from stringified results
+
+You can also pass in a custom comparison function.
+
+[![browser support](https://ci.testling.com/substack/json-stable-stringify.png)](https://ci.testling.com/substack/json-stable-stringify)
+
+[![build status](https://secure.travis-ci.org/substack/json-stable-stringify.png)](http://travis-ci.org/substack/json-stable-stringify)
+
+# example
+
+``` js
+var stringify = require('json-stable-stringify');
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+console.log(stringify(obj));
+```
+
+output:
+
+```
+{"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}
+```
+
+# methods
+
+``` js
+var stringify = require('json-stable-stringify')
+```
+
+## var str = stringify(obj, opts)
+
+Return a deterministic stringified string `str` from the object `obj`.
+
+## options
+
+### cmp
+
+If `opts` is given, you can supply an `opts.cmp` to have a custom comparison
+function for object keys. Your function `opts.cmp` is called with these
+parameters:
+
+``` js
+opts.cmp({ key: akey, value: avalue }, { key: bkey, value: bvalue })
+```
+
+For example, to sort on the object key names in reverse order you could write:
+
+``` js
+var stringify = require('json-stable-stringify');
+
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+var s = stringify(obj, function (a, b) {
+    return a.key < b.key ? 1 : -1;
+});
+console.log(s);
+```
+
+which results in the output string:
+
+```
+{"c":8,"b":[{"z":6,"y":5,"x":4},7],"a":3}
+```
+
+Or if you wanted to sort on the object values in reverse order, you could write:
+
+```
+var stringify = require('json-stable-stringify');
+
+var obj = { d: 6, c: 5, b: [{z:3,y:2,x:1},9], a: 10 };
+var s = stringify(obj, function (a, b) {
+    return a.value < b.value ? 1 : -1;
+});
+console.log(s);
+```
+
+which outputs:
+
+```
+{"d":6,"c":5,"b":[{"z":3,"y":2,"x":1},9],"a":10}
+```
+
+### space
+
+If you specify `opts.space`, it will indent the output for pretty-printing.
+Valid values are strings (e.g. `{space: \t}`) or a number of spaces
+(`{space: 3}`).
+
+For example:
+
+```js
+var obj = { b: 1, a: { foo: 'bar', and: [1, 2, 3] } };
+var s = stringify(obj, { space: '  ' });
+console.log(s);
+```
+
+which outputs:
+
+```
+{
+  "a": {
+    "and": [
+      1,
+      2,
+      3
+    ],
+    "foo": "bar"
+  },
+  "b": 1
+}
+```
+
+### replacer
+
+The replacer parameter is a function `opts.replacer(key, value)` that behaves
+the same as the replacer
+[from the core JSON object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_native_JSON#The_replacer_parameter).

+# levn [![Build Status](https://travis-ci.org/gkz/levn.png)](https://travis-ci.org/gkz/levn) <a name="levn" />
+__Light ECMAScript (JavaScript) Value Notation__
+Levn is a library which allows you to parse a string into a JavaScript value based on an expected type. It is meant for short amounts of human entered data (eg. config files, command line arguments).
+
+Levn aims to concisely describe JavaScript values in text, and allow for the extraction and validation of those values. Levn uses [type-check](https://github.com/gkz/type-check) for its type format, and to validate the results. MIT license. Version 0.3.0.
+
+__How is this different than JSON?__ levn is meant to be written by humans only, is (due to the previous point) much more concise, can be validated against supplied types, has regex and date literals, and can easily be extended with custom types. On the other hand, it is probably slower and thus less efficient at transporting large amounts of data, which is fine since this is not its purpose.
+
+    npm install levn
+
+For updates on levn, [follow me on twitter](https://twitter.com/gkzahariev).
+
+
+## Quick Examples
+
+```js
+var parse = require('levn').parse;
+parse('Number', '2');      // 2
+parse('String', '2');      // '2'
+parse('String', 'levn');   // 'levn'
+parse('String', 'a b');    // 'a b'
+parse('Boolean', 'true');  // true
+
+parse('Date', '#2011-11-11#'); // (Date object)
+parse('Date', '2011-11-11');   // (Date object)
+parse('RegExp', '/[a-z]/gi');  // /[a-z]/gi
+parse('RegExp', 're');         // /re/
+parse('Int', '2');             // 2
+
+parse('Number | String', 'str'); // 'str'
+parse('Number | String', '2');   // 2
+
+parse('[Number]', '[1,2,3]');                      // [1,2,3]
+parse('(String, Boolean)', '(hi, false)');         // ['hi', false]
+parse('{a: String, b: Number}', '{a: str, b: 2}'); // {a: 'str', b: 2}
+
+// at the top level, you can ommit surrounding delimiters
+parse('[Number]', '1,2,3');                      // [1,2,3]
+parse('(String, Boolean)', 'hi, false');         // ['hi', false]
+parse('{a: String, b: Number}', 'a: str, b: 2'); // {a: 'str', b: 2}
+
+// wildcard - auto choose type
+parse('*', '[hi,(null,[42]),{k: true}]'); // ['hi', [null, [42]], {k: true}]
+```
+## Usage
+
+`require('levn');` returns an object that exposes three properties. `VERSION` is the current version of the library as a string. `parse` and `parsedTypeParse` are functions.
+
+```js
+// parse(type, input, options);
+parse('[Number]', '1,2,3'); // [1, 2, 3]
+
+// parsedTypeParse(parsedType, input, options);
+var parsedType = require('type-check').parseType('[Number]');
+parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
+```
+
+### parse(type, input, options)
+
+`parse` casts the string `input` into a JavaScript value according to the specified `type` in the [type format](https://github.com/gkz/type-check#type-format) (and taking account the optional `options`) and returns the resulting JavaScript value.
+
+##### arguments
+* type - `String` - the type written in the [type format](https://github.com/gkz/type-check#type-format) which to check against
+* input - `String` - the value written in the [levn format](#levn-format)
+* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
+
+##### returns
+`*` - the resulting JavaScript value
+
+##### example
+```js
+parse('[Number]', '1,2,3'); // [1, 2, 3]
+```
+
+### parsedTypeParse(parsedType, input, options)
+
+`parsedTypeParse` casts the string `input` into a JavaScript value according to the specified `type` which has already been parsed (and taking account the optional `options`) and returns the resulting JavaScript value. You can parse a type using the [type-check](https://github.com/gkz/type-check) library's `parseType` function.
+
+##### arguments
+* type - `Object` - the type in the parsed type format which to check against
+* input - `String` - the value written in the [levn format](#levn-format)
+* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
+
+##### returns
+`*` - the resulting JavaScript value
+
+##### example
+```js
+var parsedType = require('type-check').parseType('[Number]');
+parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
+```
+
+## Levn Format
+
+Levn can use the type information you provide to choose the appropriate value to produce from the input. For the same input, it will choose a different output value depending on the type provided. For example, `parse('Number', '2')` will produce the number `2`, but `parse('String', '2')` will produce the string `"2"`.
+
+If you do not provide type information, and simply use `*`, levn will parse the input according the unambiguous "explicit" mode, which we will now detail - you can also set the `explicit` option to true manually in the [options](#options).
+
+* `"string"`, `'string'` are parsed as a String, eg. `"a msg"` is `"a msg"`
+* `#date#` is parsed as a Date, eg. `#2011-11-11#` is `new Date('2011-11-11')`
+* `/regexp/flags` is parsed as a RegExp, eg. `/re/gi` is `/re/gi`
+* `undefined`, `null`, `NaN`, `true`, and `false` are all their JavaScript equivalents
+* `[element1, element2, etc]` is an Array, and the casting procedure is recursively applied to each element. Eg. `[1,2,3]` is `[1,2,3]`.
+* `(element1, element2, etc)` is an tuple, and the casting procedure is recursively applied to each element. Eg. `(1, a)` is `(1, a)` (is `[1, 'a']`).
+* `{key1: val1, key2: val2, ...}` is an Object, and the casting procedure is recursively applied to each property. Eg. `{a: 1, b: 2}` is `{a: 1, b: 2}`.
+* Any test which does not fall under the above, and which does not contain special characters (`[``]``(``)``{``}``:``,`) is a string, eg. `$12- blah` is `"$12- blah"`.
+
+If you do provide type information, you can make your input more concise as the program already has some information about what it expects. Please see the [type format](https://github.com/gkz/type-check#type-format) section of [type-check](https://github.com/gkz/type-check) for more information about how to specify types. There are some rules about what levn can do with the information:
+
+* If a String is expected, and only a String, all characters of the input (including any special ones) will become part of the output. Eg. `[({})]` is `"[({})]"`, and `"hi"` is `'"hi"'`.
+* If a Date is expected, the surrounding `#` can be omitted from date literals. Eg. `2011-11-11` is `new Date('2011-11-11')`.
+* If a RegExp is expected, no flags need to be specified, and the regex is not using any of the special characters,the opening and closing `/` can be omitted - this will have the affect of setting the source of the regex to the input. Eg. `regex` is `/regex/`.
+* If an Array is expected, and it is the root node (at the top level), the opening `[` and closing `]` can be omitted. Eg. `1,2,3` is `[1,2,3]`.
+* If a tuple is expected, and it is the root node (at the top level), the opening `(` and closing `)` can be omitted. Eg. `1, a` is `(1, a)` (is `[1, 'a']`).
+* If an Object is expected, and it is the root node (at the top level), the opening `{` and closing `}` can be omitted. Eg `a: 1, b: 2` is `{a: 1, b: 2}`.
+
+If you list multiple types (eg. `Number | String`), it will first attempt to cast to the first type and then validate - if the validation fails it will move on to the next type and so forth, left to right. You must be careful as some types will succeed with any input, such as String. Thus put String at the end of your list. In non-explicit mode, Date and RegExp will succeed with a large variety of input - also be careful with these and list them near the end if not last in your list.
+
+Whitespace between special characters and elements is inconsequential.
+
+## Options
+
+Options is an object. It is an optional parameter to the `parse` and `parsedTypeParse` functions.
+
+### Explicit
+
+A `Boolean`. By default it is `false`.
+
+__Example:__
+
+```js
+parse('RegExp', 're', {explicit: false});          // /re/
+parse('RegExp', 're', {explicit: true});           // Error: ... does not type check...
+parse('RegExp | String', 're', {explicit: true});  // 're'
+```
+
+`explicit` sets whether to be in explicit mode or not. Using `*` automatically activates explicit mode. For more information, read the [levn format](#levn-format) section.
+
+### customTypes
+
+An `Object`. Empty `{}` by default.
+
+__Example:__
+
+```js
+var options = {
+  customTypes: {
+    Even: {
+      typeOf: 'Number',
+      validate: function (x) {
+        return x % 2 === 0;
+      },
+      cast: function (x) {
+        return {type: 'Just', value: parseInt(x)};
+      }
+    }
+  }
+}
+parse('Even', '2', options); // 2
+parse('Even', '3', options); // Error: Value: "3" does not type check...
+```
+
+__Another Example:__
+```js
+function Person(name, age){
+  this.name = name;
+  this.age = age;
+}
+var options = {
+  customTypes: {
+    Person: {
+      typeOf: 'Object',
+      validate: function (x) {
+        x instanceof Person;
+      },
+      cast: function (value, options, typesCast) {
+        var name, age;
+        if ({}.toString.call(value).slice(8, -1) !== 'Object') {
+          return {type: 'Nothing'};
+        }
+        name = typesCast(value.name, [{type: 'String'}], options);
+        age = typesCast(value.age, [{type: 'Numger'}], options);
+        return {type: 'Just', value: new Person(name, age)};
+    }
+  }
+}
+parse('Person', '{name: Laura, age: 25}', options); // Person {name: 'Laura', age: 25}
+```
+
+`customTypes` is an object whose keys are the name of the types, and whose values are an object with three properties, `typeOf`, `validate`, and `cast`. For more information about `typeOf` and `validate`, please see the [custom types](https://github.com/gkz/type-check#custom-types) section of type-check.
+
+`cast` is a function which receives three arguments, the value under question, options, and the typesCast function. In `cast`, attempt to cast the value into the specified type. If you are successful, return an object in the format `{type: 'Just', value: CAST-VALUE}`, if you know it won't work, return `{type: 'Nothing'}`.  You can use the `typesCast` function to cast any child values. Remember to pass `options` to it. In your function you can also check for `options.explicit` and act accordingly.
+
+## Technical About
+
+`levn` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [type-check](https://github.com/gkz/type-check) to both parse types and validate values. It also uses the [prelude.ls](http://preludels.com/) library.

+# Optionator
+<a name="optionator" />
+
+Optionator is a JavaScript option parsing and help generation library used by [eslint](http://eslint.org), [Grasp](http://graspjs.com), [LiveScript](http://livescript.net), [esmangle](https://github.com/estools/esmangle), [escodegen](https://github.com/estools/escodegen), and [many more](https://www.npmjs.com/browse/depended/optionator).
+
+For an online demo, check out the [Grasp online demo](http://www.graspjs.com/#demo).
+
+[About](#about) &middot; [Usage](#usage) &middot; [Settings Format](#settings-format) &middot; [Argument Format](#argument-format)
+
+## Why?
+The  problem with other option parsers, such as `yargs` or `minimist`, is they just accept all input, valid or not.
+With Optionator, if you mistype an option, it will give you an error (with a suggestion for what you meant).
+If you give the wrong type of argument for an option, it will give you an error rather than supplying the wrong input to your application.
+
+    $ cmd --halp
+    Invalid option '--halp' - perhaps you meant '--help'?
+
+    $ cmd --count str
+    Invalid value for option 'count' - expected type Int, received value: str.
+
+Other helpful features include reformatting the help text based on the size of the console, so that it fits even if the console is narrow, and accepting not just an array (eg. process.argv), but a string or object as well, making things like testing much easier.
+
+## About
+Optionator uses [type-check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) behind the scenes to cast and verify input according the specified types.
+
+MIT license. Version 0.8.2
+
+    npm install optionator
+
+For updates on Optionator, [follow me on twitter](https://twitter.com/gkzahariev).
+
+## Usage
+`require('optionator');` returns a function. It has one property, `VERSION`, the current version of the library as a string. This function is called with an object specifying your options and other information, see the [settings format section](#settings-format). This in turn returns an object with three properties, `parse`, `parseArgv`, `generateHelp`, and `generateHelpForOption`, which are all functions.
+
+```js
+var optionator = require('optionator')({
+    prepend: 'Usage: cmd [options]',
+    append: 'Version 1.0.0',
+    options: [{
+        option: 'help',
+        alias: 'h',
+        type: 'Boolean',
+        description: 'displays help'
+    }, {
+        option: 'count',
+        alias: 'c',
+        type: 'Int',
+        description: 'number of things',

+
+### parse(input, parseOptions)
+`parse` processes the `input` according to your settings, and returns an object with the results.
+
+##### arguments
+* input - `[String] | Object | String` - the input you wish to parse
+* parseOptions - `{slice: Int}` - all options optional
+    - `slice` specifies how much to slice away from the beginning if the input is an array or string - by default `0` for string, `2` for array (works with `process.argv`)
+
+##### returns
+`Object` - the parsed options, each key is a camelCase version of the option name (specified in dash-case), and each value is the processed value for that option. Positional values are in an array under the `_` key.
+
+##### example
+```js
+parse(['node', 't.js', '--count', '2', 'positional']); // {count: 2, _: ['positional']}
+parse('--count 2 positional');                         // {count: 2, _: ['positional']}
+parse({count: 2, _:['positional']});                   // {count: 2, _: ['positional']}
+```
+
+### parseArgv(input)
+`parseArgv` works exactly like `parse`, but only for array input and it slices off the first two elements.
+
+##### arguments
+* input - `[String]` - the input you wish to parse
+
+##### returns
+See "returns" section in "parse"
+
+##### example
+```js
+parseArgv(process.argv);
+```
+
+### generateHelp(helpOptions)
+`generateHelp` produces help text based on your settings.
+
+##### arguments
+* helpOptions - `{showHidden: Boolean, interpolate: Object}` - all options optional
+    - `showHidden` specifies whether to show options with `hidden: true` specified, by default it is `false`
+    - `interpolate` specify data to be interpolated in `prepend` and `append` text, `{{key}}` is the format - eg. `generateHelp({interpolate:{version: '0.4.2'}})`, will change this `append` text: `Version {{version}}` to `Version 0.4.2`
+
+##### returns
+`String` - the generated help text
+
+##### example
+```js
+generateHelp(); /*
+"Usage: cmd [options] positional
+
+  -h, --help       displays help
+  -c, --count Int  number of things
+
+Version  1.0.0
+"*/
+```
+
+### generateHelpForOption(optionName)
+`generateHelpForOption` produces expanded help text for the specified with `optionName` option. If an `example` was specified for the option, it will be displayed,  and if a `longDescription` was specified, it will display that instead of the `description`.
+
+##### arguments
+* optionName - `String` - the name of the option to display
+
+##### returns
+`String` - the generated help text for the option
+
+##### example
+```js
+generateHelpForOption('count'); /*
+"-c, --count Int
+description: number of things
+example: cmd --count 2
+"*/
+```
+
+## Settings Format
+When your `require('optionator')`, you get a function that takes in a settings object. This object has the type:
+
+    {
+      prepend: String,
+      append: String,
+      options: [{heading: String} | {
+        option: String,
+        alias: [String] | String,
+        type: String,
+        enum: [String],
+        default: String,
+        restPositional: Boolean,
+        required: Boolean,
+        overrideRequired: Boolean,
+        dependsOn: [String] | String,
+        concatRepeatedArrays: Boolean | (Boolean, Object),
+        mergeRepeatedObjects: Boolean,
+        description: String,
+        longDescription: String,
+        example: [String] | String
+      }],
+      helpStyle: {
+        aliasSeparator: String,
+        typeSeparator: String,
+        descriptionSeparator: String,
+        initialIndent: Int,
+        secondaryIndent: Int,
+        maxPadFactor: Number
+      },
+      mutuallyExclusive: [[String | [String]]],
+      concatRepeatedArrays: Boolean | (Boolean, Object), // deprecated, set in defaults object
+      mergeRepeatedObjects: Boolean, // deprecated, set in defaults object
+      positionalAnywhere: Boolean,
+      typeAliases: Object,
+      defaults: Object
+    }
+
+All of the properties are optional (the `Maybe` has been excluded for brevities sake), except for having either `heading: String` or `option: String` in each object in the `options` array.
+
+### Top Level Properties
+* `prepend` is an optional string to be placed before the options in the help text
+* `append` is an optional string to be placed after the options in the help text
+* `options` is a required array specifying your options and headings, the options and headings will be displayed in the order specified
+* `helpStyle` is an optional object which enables you to change the default appearance of some aspects of the help text
+* `mutuallyExclusive` is an optional array of arrays of either strings or arrays of strings. The top level array is a list of rules, each rule is a list of elements - each element can be either a string (the name of an option), or a list of strings (a group of option names) - there will be an error if more than one element is present
+* `concatRepeatedArrays` see description under the "Option Properties" heading - use at the top level is deprecated, if you want to set this for all options, use the `defaults` property
+* `mergeRepeatedObjects` see description under the "Option Properties" heading - use at the top level is deprecated, if you want to set this for all options, use the `defaults` property
+* `positionalAnywhere` is an optional boolean (defaults to `true`) - when `true` it allows positional arguments anywhere, when `false`, all arguments after the first positional one are taken to be positional as well, even if they look like a flag. For example, with `positionalAnywhere: false`, the arguments `--flag --boom 12 --crack` would have two positional arguments: `12` and `--crack`
+* `typeAliases` is an optional object, it allows you to set aliases for types, eg. `{Path: 'String'}` would allow you to use the type `Path` as an alias for the type `String`
+* `defaults` is an optional object following the option properties format, which specifies default values for all options. A default will be overridden if manually set. For example, you can do `default: { type: "String" }` to set the default type of all options to `String`, and then override that default in an individual option by setting the `type` property
+
+#### Heading Properties
+* `heading` a required string, the name of the heading
+
+#### Option Properties
+* `option` the required name of the option - use dash-case, without the leading dashes
+* `alias` is an optional string or array of strings which specify any aliases for the option
+* `type` is a required string in the [type check](https://github.com/gkz/type-check) [format](https://github.com/gkz/type-check#type-format), this will be used to cast the inputted value and validate it
+* `enum` is an optional array of strings, each string will be parsed by [levn](https://github.com/gkz/levn) - the argument value must be one of the resulting values - each potential value must validate against the specified `type`
+* `default` is a optional string, which will be parsed by [levn](https://github.com/gkz/levn) and used as the default value if none is set - the value must validate against the specified `type`
+* `restPositional` is an optional boolean - if set to `true`, everything after the option will be taken to be a positional argument, even if it looks like a named argument
+* `required` is an optional boolean - if set to `true`, the option parsing will fail if the option is not defined
+* `overrideRequired` is a optional boolean - if set to `true` and the option is used, and there is another option which is required but not set, it will override the need for the required option and there will be no error - this is useful if you have required options and want to use `--help` or `--version` flags
+* `concatRepeatedArrays` is an optional boolean or tuple with boolean and options object (defaults to `false`) - when set to `true` and an option contains an array value and is repeated, the subsequent values for the flag will be appended rather than overwriting the original value - eg. option `g` of type `[String]`: `-g a -g b -g c,d` will result in `['a','b','c','d']`
+
+ You can supply an options object by giving the following value: `[true, options]`. The one currently supported option is `oneValuePerFlag`, this only allows one array value per flag. This is useful if your potential values contain a comma.
+* `mergeRepeatedObjects` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an object value and is repeated, the subsequent values for the flag will be merged rather than overwriting the original value - eg. option `g` of type `Object`: `-g a:1 -g b:2 -g c:3,d:4` will result in `{a: 1, b: 2, c: 3, d: 4}`
+* `dependsOn` is an optional string or array of strings - if simply a string (the name of another option), it will make sure that that other option is set, if an array of strings, depending on whether `'and'` or `'or'` is first, it will either check whether all (`['and', 'option-a', 'option-b']`), or at least one (`['or', 'option-a', 'option-b']`) other options are set
+* `description` is an optional string, which will be displayed next to the option in the help text
+* `longDescription` is an optional string, it will be displayed instead of the `description` when `generateHelpForOption` is used
+* `example` is an optional string or array of strings with example(s) for the option - these will be displayed when `generateHelpForOption` is used
+
+#### Help Style Properties
+* `aliasSeparator` is an optional string, separates multiple names from each other - default: ' ,'
+* `typeSeparator` is an optional string, separates the type from the names - default: ' '
+* `descriptionSeparator` is an optional string , separates the description from the padded name and type - default: '  '
+* `initialIndent` is an optional int - the amount of indent for options - default: 2
+* `secondaryIndent` is an optional int - the amount of indent if wrapped fully (in addition to the initial indent) - default: 4
+* `maxPadFactor` is an optional number - affects the default level of padding for the names/type, it is multiplied by the average of the length of the names/type - default: 1.5
+
+## Argument Format
+At the highest level there are two types of arguments: named, and positional.
+
+Name arguments of any length are prefixed with `--` (eg. `--go`), and those of one character may be prefixed with either `--` or `-` (eg. `-g`).
+
+There are two types of named arguments: boolean flags (eg. `--problemo`, `-p`) which take no value and result in a `true` if they are present, the falsey `undefined` if they are not present, or `false` if present and explicitly prefixed with `no` (eg. `--no-problemo`). Named arguments with values (eg. `--tseries 800`, `-t 800`) are the other type. If the option has a type `Boolean` it will automatically be made into a boolean flag. Any other type results in a named argument that takes a value.
+
+For more information about how to properly set types to get the value you want, take a look at the [type check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) pages.
+
+You can group single character arguments that use a single `-`, however all except the last must be boolean flags (which take no value). The last may be a boolean flag, or an argument which takes a value - eg. `-ba 2` is equivalent to `-b -a 2`.
+
+Positional arguments are all those values which do not fall under the above - they can be anywhere, not just at the end. For example, in `cmd -b one -a 2 two` where `b` is a boolean flag, and `a` has the type `Number`, there are two positional arguments, `one` and `two`.
+
+Everything after an `--` is positional, even if it looks like a named argument.
+
+You may optionally use `=` to separate option names from values, for example: `--count=2`.
+
+If you specify the option `NUM`, then any argument using a single `-` followed by a number will be valid and will set the value of `NUM`. Eg. `-2` will be parsed into `NUM: 2`.
+
+If duplicate named arguments are present, the last one will be taken.
+
+## Technical About
+`optionator` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [levn](https://github.com/gkz/levn) to cast arguments to their specified type, and uses [type-check](https://github.com/gkz/type-check) to validate values. It also uses the [prelude.ls](http://preludels.com/) library.
