+# [![Jade - template engine ](http://i.imgur.com/5zf2aVt.png)](http://jade-lang.com/)
+
+Full documentation is at [jade-lang.com](http://jade-lang.com/)
+
+ Jade is a high performance template engine heavily influenced by [Haml](http://haml-lang.com)
+ and implemented with JavaScript for [node](http://nodejs.org). For discussion join the [Google Group](http://groups.google.com/group/jadejs).
+
+ You can test drive Jade online [here](http://naltatis.github.com/jade-syntax-docs).
+
+ [![Build Status](https://travis-ci.org/visionmedia/jade.png?branch=master)](https://travis-ci.org/visionmedia/jade)
+ [![Dependency Status](https://gemnasium.com/visionmedia/jade.png)](https://gemnasium.com/visionmedia/jade)
+ [![NPM version](https://badge.fury.io/js/jade.png)](http://badge.fury.io/js/jade)
+
+## Announcements
+
+**Deprecation of implicit script/style text-only:**
+
+ Jade version 0.31.0 deprecated implicit text only support for scripts and styles.  To fix this all you need to do is add a `.` character after the script or style tag.
+
+ It is hoped that this change will make Jade easier for newcomers to learn without affecting the power of the language or leading to excessive verboseness.
+
+ If you have a lot of Jade files that need fixing you can use [fix-jade](https://github.com/ForbesLindesay/fix-jade) to attempt to automate the process.
+
+**Command line option change:**
+
+since `v0.31.0`, `-o` is preferred for `--out` where we used `-O` before.
+
+## Installation
+
+via npm:
+
+```bash
+$ npm install jade
+```
+
+## Syntax
+
+Jade is a clean, whitespace sensitive syntax for writing html.  Here is a simple example:
+
+```jade
+doctype html
+html(lang="en")
+  head
+    title= pageTitle
+    script(type='text/javascript').
+      if (foo) bar(1 + 5)
+  body
+    h1 Jade - node template engine
+    #container.col
+      if youAreUsingJade
+        p You are amazing
+      else
+        p Get on it!
+      p.
+        Jade is a terse and simple templating language with a
+        strong focus on performance and powerful features.
+```
+
+becomes
+
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <title>Jade</title>
+    <script type="text/javascript">
+      if (foo) bar(1 + 5)
+    </script>
+  </head>
+  <body>
+    <h1>Jade - node template engine</h1>
+    <div id="container" class="col">
+      <p>You are amazing</p>
+      <p>Jade is a terse and simple templating language with a strong focus on performance and powerful features.</p>
+    </div>
+  </body>
+</html>
+```
+
+The official [jade tutorial](http://jade-lang.com/tutorial/) is a great place to start.  While that (and the syntax documentation) is being finished, you can view some of the old documentation [here](https://github.com/visionmedia/jade/blob/master/jade.md) and [here](https://github.com/visionmedia/jade/blob/master/jade-language.md)
+
+## API
+
+For full API, see [jade-lang.com/api](http://jade-lang.com/api/)
+
+```js
+var jade = require('jade');
+
+// compile
+var fn = jade.compile('string of jade', options);
+var html = fn(locals);
+
+// render
+var html = jade.render('string of jade', merge(options, locals));
+
+// renderFile
+var html = jade.renderFile('filename.jade', merge(options, locals));
+```
+
+### Options
+
+ - `filename`  Used in exceptions, and required when using includes
+ - `compileDebug`  When `false` no debug instrumentation is compiled
+ - `pretty`    Add pretty-indentation whitespace to output _(false by default)_
+
+## Browser Support
+
+ The latest version of jade can be download for the browser in standalone form from [here](https://github.com/visionmedia/jade/raw/master/jade.js).  It only supports the very latest browsers though, and is a large file.  It is recommended that you pre-compile your jade templates to JavaScript and then just use the [runtime.js](https://github.com/visionmedia/jade/raw/master/runtime.js) library on the client.
+
+ To compile a template for use on the client using the command line, do:
+
+```console
+$ jade --client --no-debug filename.jade
+```
+
+which will produce `filename.js` containing the compiled template.
+
+## Command Line
+
+After installing the latest version of [node](http://nodejs.org/), install with:
+
+```console
+$ npm install jade -g
+```
+
+and run with
+
+```console
+$ jade --help
+```

+# Jade
+
+  The jade template engine for node.js
+
+## Synopsis
+
+    jade [-h|--help] [-v|--version] [-o|--obj STR]
+         [-O|--out DIR] [-p|--path PATH] [-P|--pretty]
+         [-c|--client] [-D|--no-debug]
+
+## Examples
+
+  translate jade the templates dir
+
+    $ jade templates
+
+  create {foo,bar}.html
+
+    $ jade {foo,bar}.jade
+
+  jade over stdio
+
+    $ jade < my.jade > my.html
+
+  jade over s
+
+    $ echo "h1 Jade!" | jade
+
+  foo, bar dirs rendering to /tmp
+
+    $ jade foo bar --out /tmp
+
+  compile client-side templates without debugging
+  instrumentation, making the output javascript
+  very light-weight. This requires runtime.js
+  in your projects.
+
+     $ jade --client --no-debug < my.jade
+
+## Tags
+
+  Tags are simply nested via whitespace, closing
+  tags defined for you. These indents are called "blocks".
+  
+    ul
+      li
+        a Foo
+      li
+        a Bar
+
+  You may have several tags in one "block":
+  
+    ul
+      li
+        a Foo
+        a Bar
+        a Baz
+
+## Self-closing Tags
+
+  Some tags are flagged as self-closing by default, such
+  as `meta`, `link`, and so on. To explicitly self-close
+  a tag simply append the `/` character:
+
+     foo/
+     foo(bar='baz')/
+
+  Would yield:
+  
+     <foo/>
+     <foo bar="baz"/>
+
+## Attributes
+
+  Tag attributes look similar to HTML, however
+  the values are regular JavaScript, here are
+  some examples:
+  
+    a(href='google.com') Google
+    a(class='button', href='google.com') Google
+
+  As mentioned the attribute values are just JavaScript,
+  this means ternary operations and other JavaScript expressions
+  work just fine:
+  
+    body(class=user.authenticated ? 'authenticated' : 'anonymous')
+    a(href=user.website || 'http://google.com')
+
+  Multiple lines work too:
+
+    input(type='checkbox',
+      name='agreement',
+      checked)
+
+  Multiple lines without the comma work fine:
+
+    input(type='checkbox'
+      name='agreement'
+      checked)
+
+  Funky whitespace? fine:
+
+    input(
+      type='checkbox'
+      name='agreement'
+      checked)
+
+## Boolean attributes
+
+  Boolean attributes are mirrored by Jade, and accept
+  bools, aka _true_ or _false_. When no value is specified
+  _true_ is assumed. For example:
+  
+    input(type="checkbox", checked)
+    // => "<input type="checkbox" checked="checked" />"
+
+  For example if the checkbox was for an agreement, perhaps `user.agreed`
+  was _true_ the following would also output 'checked="checked"':
+  
+     input(type="checkbox", checked=user.agreed)
+
+## Class attributes
+
+  The _class_ attribute accepts an array of classes,
+  this can be handy when generated from a javascript
+  function etc:
+  
+    classes = ['foo', 'bar', 'baz']
+    a(class=classes)
+    // => "<a class="foo bar baz"></a>"
+
+## Class literal
+
+  Classes may be defined using a ".CLASSNAME" syntax:
+  
+     .button
+     // => "<div class="button"></div>"
+  
+  Or chained:
+  
+     .large.button
+     // => "<div class="large button"></div>"
+
+  The previous defaulted to divs, however you
+  may also specify the tag type:
+  
+      h1.title My Title
+      // => "<h1 class="title">My Title</h1>"
+
+## Id literal
+
+  Much like the class literal there's an id literal:
+  
+    #user-1
+    // => "<div id="user-1"></div>"
+
+  Again we may specify the tag as well:
+  
+    ul#menu
+      li: a(href='/home') Home
+      li: a(href='/store') Store
+      li: a(href='/contact') Contact
+
+  Finally all of these may be used in any combination,
+  the following are all valid tags:
+  
+    a.button#contact(style: 'color: red') Contact
+    a.button(style: 'color: red')#contact Contact
+    a(style: 'color: red').button#contact Contact
+
+## Block expansion
+
+  Jade supports the concept of "block expansion", in which
+  using a trailing ":" after a tag will inject a block:
+  
+    ul
+      li: a Foo
+      li: a Bar
+      li: a Baz
+
+## Text
+
+   Arbitrary text may follow tags:
+   
+     p Welcome to my site
+  
+  yields:
+  
+     <p>Welcome to my site</p>
+
+## Pipe text
+
+  Another form of text is "pipe" text. Pipes act
+  as the text margin for large bodies of text.
+
+    p
+      | This is a large
+      | body of text for
+      | this tag.
+      | 
+      | Nothing too
+      | exciting.
+
+  yields:
+  
+    <p>This is a large
+    body of text for
+    this tag.
+
+    Nothing too
+    exciting.
+    </p>
+
+  Using pipes we can also specify regular Jade tags
+  within the text:
+  
+    p
+      | Click to visit
+      a(href='http://google.com') Google
+      | if you want.
+
+## Text only tags
+
+  As an alternative to pipe text you may add
+  a trailing "." to indicate that the block
+  contains nothing but plain-text, no tags:
+
+    p.
+      This is a large
+      body of text for
+      this tag.
+
+      Nothing too
+      exciting.
+
+  Some tags are text-only by default, for example
+  _script_, _textarea_, and _style_ tags do not
+  contain nested HTML so Jade implies the trailing ".":
+  
+    script
+      if (foo) {
+        bar();
+      }
+
+    style
+      body {
+        padding: 50px;
+        font: 14px Helvetica;
+      }
+
+## Template script tags
+
+  Sometimes it's useful to define HTML in script
+  tags using Jade, typically for client-side templates.
+  
+  To do this simply give the _script_ tag an arbitrary
+  _type_ attribute such as _text/x-template_:
+  
+    script(type='text/template')
+      h1 Look!
+      p Jade still works in here!
+
+## Interpolation
+
+  Both plain-text and piped-text support interpolation,
+  which comes in two forms, escapes and non-escaped. The
+  following will output the _user.name_ in the paragraph
+  but HTML within it will be escaped to prevent XSS attacks:
+  
+    p Welcome #{user.name}
+
+  The following syntax is identical however it will _not_ escape
+  HTML, and should only be used with strings that you trust:
+  
+    p Welcome !{user.name}
+  
+## Inline HTML
+
+  Sometimes constructing small inline snippets of HTML
+  in Jade can be annoying, luckily we can add plain
+  HTML as well:
+  
+    p Welcome <em>#{user.name}</em>
+
+## Code
+
+  To buffer output with Jade simply use _=_ at the beginning
+  of a line or after a tag. This method escapes any HTML
+  present in the string.
+  
+    p= user.description
+    
+  To buffer output unescaped use the _!=_ variant, but again
+  be careful of XSS.
+  
+    p!= user.description
+  
+  The final way to mess with JavaScript code in Jade is the unbuffered
+  _-_, which can be used for conditionals, defining variables etc:
+  
+    - var user = { description: 'foo bar baz' }
+    #user
+      - if (user.description) {
+        h2 Description
+        p.description= user.description
+      - }
+
+   When compiled blocks are wrapped in anonymous functions, so the
+   following is also valid, without braces:
+   
+     - var user = { description: 'foo bar baz' }
+     #user
+       - if (user.description)
+         h2 Description
+         p.description= user.description
+
+   If you really want you could even use `.forEach()` and others:
+   
+    - users.forEach(function(user){
+      .user
+        h2= user.name
+        p User #{user.name} is #{user.age} years old
+    - })
+
+   Taking this further Jade provides some syntax for conditionals,
+   iteration, switch statements etc. Let's look at those next!
+
+## Assignment
+
+  Jade's first-class assignment is simple, simply use the _=_
+  operator and Jade will _var_ it for you. The following are equivalent:
+  
+    - var user = { name: 'tobi' }
+    user = { name: 'tobi' }
+
+## Conditionals
+
+  Jade's first-class conditional syntax allows for optional
+  parenthesis, and you may now omit the leading _-_ otherwise
+  it's identical, still just regular javascript:
+  
+    user = { description: 'foo bar baz' }
+    #user
+      if user.description
+        h2 Description
+        p.description= user.description
+
+  Jade provides the negated version, _unless_ as well, the following
+  are equivalent:
+  
+    - if (!(user.isAnonymous))
+      p You're logged in as #{user.name}
+
+    unless user.isAnonymous
+      p You're logged in as #{user.name}
+
+## Iteration
+
+  JavaScript's _for_ loops don't look very declarative, so Jade
+  also provides its own _for_ loop construct, aliased as _each_:
+
+    for user in users
+      .user
+        h2= user.name
+        p user #{user.name} is #{user.age} year old
+
+   As mentioned _each_ is identical:
+   
+     each user in users
+       .user
+         h2= user.name
+
+   If necessary the index is available as well:
+   
+      for user, i in users
+        .user(class='user-#{i}')
+          h2= user.name
+
+   Remember, it's just JavaScript:
+   
+      ul#letters
+        for letter in ['a', 'b', 'c']
+          li= letter
+
+## Mixins
+
+  Mixins provide a way to define jade "functions" which "mix in"
+  their contents when called. This is useful for abstracting
+  out large fragments of Jade.
+
+  The simplest possible mixin which accepts no arguments might
+  look like this:
+  
+      mixin hello
+        p Hello
+
+   You use a mixin by placing `+` before the name:
+
+      +hello
+
+   For something a little more dynamic, mixins can take
+   arguments, the mixin itself is converted to a javascript
+   function internally:
+   
+       mixin hello(user)
+         p Hello #{user}
+
+       +hello('Tobi')
+  
+   Yields:
+
+       <p>Hello Tobi</p>
+
+  Mixins may optionally take blocks, when a block is passed
+  its contents becomes the implicit `block` argument. For
+  example here is a mixin passed a block, and also invoked
+  without passing a block:
+
+      mixin article(title)
+        .article
+          .article-wrapper
+            h1= title
+            if block
+              block
+            else
+              p No content provided
+      
+      +article('Hello world')
+      
+      +article('Hello world')
+        p This is my
+        p Amazing article
+
+   yields:
+   
+       <div class="article">
+         <div class="article-wrapper">
+           <h1>Hello world</h1>
+           <p>No content provided</p>
+         </div>
+       </div>
+
+       <div class="article">
+         <div class="article-wrapper">
+           <h1>Hello world</h1>
+           <p>This is my</p>
+           <p>Amazing article</p>
+         </div>
+       </div>
+
+  Mixins can even take attributes, just like a tag. When
+  attributes are passed they become the implicit `attributes`
+  argument. Individual attributes can be accessed just like
+  normal object properties:
+  
+      mixin centered
+        .centered(class=attributes.class)
+          block
+      
+      +centered.bold Hello world
+      
+      +centered.red
+        p This is my
+        p Amazing article
+  
+   yields:
+   
+       <div class="centered bold">Hello world</div>
+       <div class="centered red">
+         <p>This is my</p>
+         <p>Amazing article</p>
+       </div>
+  
+   If you use `attributes` directly, *all* passed attributes
+   get used:
+   
+      mixin link
+        a.menu(attributes)
+          block
+      
+      +link.highlight(href='#top') Top
+      +link#sec1.plain(href='#section1') Section 1
+      +link#sec2.plain(href='#section2') Section 2
+  
+   yields:
+   
+       <a href="#top" class="highlight menu">Top</a>
+       <a id="sec1" href="#section1" class="plain menu">Section 1</a>
+       <a id="sec2" href="#section2" class="plain menu">Section 2</a>
+   
+   If you pass arguments, they must directly follow the mixin:
+   
+      mixin list(arr)
+        if block
+          .title
+            block
+        ul(attributes)
+          each item in arr
+            li= item
+      
+      +list(['foo', 'bar', 'baz'])(id='myList', class='bold')
+  
+   yields:
+   
+       <ul id="myList" class="bold">
+         <li>foo</li>
+         <li>bar</li>
+         <li>baz</li>
+       </ul>

+# character-parser
+
+Parse JavaScript one character at a time to look for snippets in Templates.  This is not a validator, it's just designed to allow you to have sections of JavaScript delimited by brackets robustly.
+
+[![Build Status](https://travis-ci.org/ForbesLindesay/character-parser.png?branch=master)](https://travis-ci.org/ForbesLindesay/character-parser)
+
+## Installation
+
+    npm install character-parser
+
+## Usage
+
+Work out how much depth changes:
+
+```js
+var state = parse('foo(arg1, arg2, {\n  foo: [a, b\n');
+assert(state.roundDepth === 1);
+assert(state.curlyDepth === 1);
+assert(state.squareDepth === 1);
+parse('    c, d]\n  })', state);
+assert(state.squareDepth === 0);
+assert(state.curlyDepth === 0);
+assert(state.roundDepth === 0);
+```
+
+### Bracketed Expressions
+
+Find all the contents of a bracketed expression:
+
+```js
+var section = parser.parseMax('foo="(", bar="}") bing bong');
+assert(section.start === 0);
+assert(section.end === 16);//exclusive end of string
+assert(section.src = 'foo="(", bar="}"');
+
+
+var section = parser.parseMax('{foo="(", bar="}"} bing bong', {start: 1});
+assert(section.start === 1);
+assert(section.end === 17);//exclusive end of string
+assert(section.src = 'foo="(", bar="}"');
+```
+
+The bracketed expression parsing simply parses up to but excluding the first unmatched closed bracket (`)`, `}`, `]`).  It is clever enough to ignore brackets in comments or strings.
+
+
+### Custom Delimited Expressions
+
+Find code up to a custom delimiter:
+
+```js
+var section = parser.parseUntil('foo.bar("%>").baz%> bing bong', '%>');
+assert(section.start === 0);
+assert(section.end === 17);//exclusive end of string
+assert(section.src = 'foo.bar("%>").baz');
+
+var section = parser.parseUntil('<%foo.bar("%>").baz%> bing bong', '%>', {start: 2});
+assert(section.start === 2);
+assert(section.end === 19);//exclusive end of string
+assert(section.src = 'foo.bar("%>").baz');
+```
+
+Delimiters are ignored if they are inside strings or comments.
+
+## API
+
+### parse(str, state = defaultState(), options = {start: 0, end: src.length})
+
+Parse a string starting at the index start, and return the state after parsing that string.
+
+If you want to parse one string in multiple sections you should keep passing the resulting state to the next parse operation.
+
+Returns a `State` object.
+
+### parseMax(src, options = {start: 0})
+
+Parses the source until the first unmatched close bracket (any of `)`, `}`, `]`).  It returns an object with the structure:
+
+```js
+{
+  start: 0,//index of first character of string
+  end: 13,//index of first character after the end of string
+  src: 'source string'
+}
+```
+
+### parseUntil(src, delimiter, options = {start: 0, includeLineComment: false})
+
+Parses the source until the first occurence of `delimiter` which is not in a string or a comment.  If `includeLineComment` is `true`, it will still count if the delimiter occurs in a line comment, but not in a block comment.  It returns an object with the structure:
+
+```js
+{
+  start: 0,//index of first character of string
+  end: 13,//index of first character after the end of string
+  src: 'source string'
+}
+```
+
+### parseChar(character, state = defaultState())
+
+Parses the single character and returns the state.  See `parse` for the structure of the returned state object.  N.B. character must be a single character not a multi character string.
+
+### defaultState()
+
+Get a default starting state.
+
+### isPunctuator(character)
+
+Returns `true` if `character` represents punctuation in JavaScript.
+
+### isKeyword(name)
+
+Returns `true` if `name` is a keyword in JavaScript.
+
+## State
+
+A state is an object with the following structure
+
+```js
+{
+  lineComment: false, //true if inside a line comment
+  blockComment: false, //true if inside a block comment
+
+  singleQuote: false, //true if inside a single quoted string
+  doubleQuote: false, //true if inside a double quoted string
+  regexp:      false, //true if inside a regular expression
+  escaped: false, //true if in a string and the last character was an escape character
+
+  roundDepth: 0, //number of un-closed open `(` brackets
+  curlyDepth: 0, //number of un-closed open `{` brackets
+  squareDepth: 0 //number of un-closed open `[` brackets
+}
+```
+
+It also has the following useful methods:
+
+- `.isString()` returns `true` if the current location is inside a string.
+- `.isComment()` returns `true` if the current location is inside a comment.
+- `isNesting()` returns `true` if the current location is anything but at the top level, i.e. with no nesting.

It is clever enough to ignore brackets in comments or strings.\r\n\r\n\r\n### Custom Delimited Expressions\r\n\r\nFind code up to a custom delimiter:\r\n\r\n```js\r\nvar section = parser.parseUntil('foo.bar(\"%>\").baz%> bing bong', '%>');\r\nassert(section.start === 0);\r\nassert(section.end === 17);//exclusive end of string\r\nassert(section.src = 'foo.bar(\"%>\").baz');\r\n\r\nvar section = parser.parseUntil('<%foo.bar(\"%>\").baz%> bing bong', '%>', {start: 2});\r\nassert(section.start === 2);\r\nassert(section.end === 19);//exclusive end of string\r\nassert(section.src = 'foo.bar(\"%>\").baz');\r\n```\r\n\r\nDelimiters are ignored if they are inside strings or comments.\r\n\r\n## API\r\n\r\n### parse(str, state = defaultState(), options = {start: 0, end: src.length})\r\n\r\nParse a string starting at the index start, and return the state after parsing that string.\r\n\r\nIf you want to parse one string in multiple sections you should keep passing the resulting state to the next parse operation.\r\n\r\nReturns a `State` object.\r\n\r\n### parseMax(src, options = {start: 0})\r\n\r\nParses the source until the first unmatched close bracket (any of `)`, `}`, `]`).  It returns an object with the structure:\r\n\r\n```js\r\n{\r\n  start: 0,//index of first character of string\r\n  end: 13,//index of first character after the end of string\r\n  src: 'source string'\r\n}\r\n```\r\n\r\n### parseUntil(src, delimiter, options = {start: 0, includeLineComment: false})\r\n\r\nParses the source until the first occurence of `delimiter` which is not in a string or a comment.  If `includeLineComment` is `true`, it will still count if the delimiter occurs in a line comment, but not in a block comment.  It returns an object with the structure:\r\n\r\n```js\r\n{\r\n  start: 0,//index of first character of string\r\n  end: 13,//index of first character after the end of string\r\n  src: 'source string'\r\n}\r\n```\r\n\r\n### parseChar(character, state = defaultState())\r\n\r\nParses the single character and returns the state.  See `parse` for the structure of the returned state object.  N.B. character must be a single character not a multi character string.\r\n\r\n### defaultState()\r\n\r\nGet a default starting state.\r\n\r\n### isPunctuator(character)\r\n\r\nReturns `true` if `character` represents punctuation in JavaScript.\r\n\r\n### isKeyword(name)\r\n\r\nReturns `true` if `name` is a keyword in JavaScript.\r\n\r\n## State\r\n\r\nA state is an object with the following structure\r\n\r\n```js\r\n{\r\n  lineComment: false, //true if inside a line comment\r\n  blockComment: false, //true if inside a block comment\r\n\r\n  singleQuote: false, //true if inside a single quoted string\r\n  doubleQuote: false, //true if inside a double quoted string\r\n  regexp:      false, //true if inside a regular expression\r\n  escaped: false, //true if in a string and the last character was an escape character\r\n\r\n  roundDepth: 0, //number of un-closed open `(` brackets\r\n  curlyDepth: 0, //number of un-closed open `{` brackets\r\n  squareDepth: 0 //number of un-closed open `[` brackets\r\n}\r\n```\r\n\r\nIt also has the following useful methods:\r\n\r\n- `.isString()` returns `true` if the current location is inside a string.\r\n- `.isComment()` returns `true` if the current location is inside a comment.\r\n- `isNesting()` returns `true` if the current location is anything but at the top level, i.e. with no nesting.\r\n\r\n## License\r\n\r\nMIT",

+# Commander.js
+
+  The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/visionmedia/commander).
+
+ [![Build Status](https://secure.travis-ci.org/visionmedia/commander.js.png)](http://travis-ci.org/visionmedia/commander.js)
+
+## Installation
+
+    $ npm install commander
+
+## Option parsing
+
+ Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .version('0.0.1')
+  .option('-p, --peppers', 'Add peppers')
+  .option('-P, --pineapple', 'Add pineapple')
+  .option('-b, --bbq', 'Add bbq sauce')
+  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
+  .parse(process.argv);
+
+console.log('you ordered a pizza with:');
+if (program.peppers) console.log('  - peppers');
+if (program.pineapple) console.log('  - pineapple');
+if (program.bbq) console.log('  - bbq');
+console.log('  - %s cheese', program.cheese);
+```
+
+ Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
+
+## Automated --help
+
+ The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
+
+```  
+ $ ./examples/pizza --help
+
+   Usage: pizza [options]
+
+   Options:
+
+     -V, --version        output the version number
+     -p, --peppers        Add peppers
+     -P, --pineapple      Add pineapple
+     -b, --bbq            Add bbq sauce
+     -c, --cheese <type>  Add the specified type of cheese [marble]
+     -h, --help           output usage information
+
+```
+
+## Coercion
+
+```js
+function range(val) {
+  return val.split('..').map(Number);
+}
+
+function list(val) {
+  return val.split(',');
+}
+
+program
+  .version('0.0.1')
+  .usage('[options] <file ...>')
+  .option('-i, --integer <n>', 'An integer argument', parseInt)
+  .option('-f, --float <n>', 'A float argument', parseFloat)
+  .option('-r, --range <a>..<b>', 'A range', range)
+  .option('-l, --list <items>', 'A list', list)
+  .option('-o, --optional [value]', 'An optional value')
+  .parse(process.argv);
+
+console.log(' int: %j', program.integer);
+console.log(' float: %j', program.float);
+console.log(' optional: %j', program.optional);
+program.range = program.range || [];
+console.log(' range: %j..%j', program.range[0], program.range[1]);
+console.log(' list: %j', program.list);
+console.log(' args: %j', program.args);
+```
+
+## Custom help
+
+ You can display arbitrary `-h, --help` information
+ by listening for "--help". Commander will automatically
+ exit once you are done so that the remainder of your program
+ does not execute causing undesired behaviours, for example
+ in the following executable "stuff" will not output when
+ `--help` is used.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('../');
+
+function list(val) {
+  return val.split(',').map(Number);
+}
+
+program
+  .version('0.0.1')
+  .option('-f, --foo', 'enable some foo')
+  .option('-b, --bar', 'enable some bar')
+  .option('-B, --baz', 'enable some baz');
+
+// must be before .parse() since
+// node's emit() is immediate
+
+program.on('--help', function(){
+  console.log('  Examples:');
+  console.log('');
+  console.log('    $ custom-help --help');
+  console.log('    $ custom-help -h');
+  console.log('');
+});
+
+program.parse(process.argv);
+
+console.log('stuff');
+```
+
+yielding the following help output:
+
+```
+
+Usage: custom-help [options]
+
+Options:
+
+  -h, --help     output usage information
+  -V, --version  output the version number
+  -f, --foo      enable some foo
+  -b, --bar      enable some bar
+  -B, --baz      enable some baz
+
+Examples:
+
+  $ custom-help --help
+  $ custom-help -h
+
+```
+
+## .outputHelp()
+
+  Output help information without exiting.
+
+## .help()
+
+  Output help information and exit immediately.

+# constantinople
+
+Determine whether a JavaScript expression evaluates to a constant (using UglifyJS).  Here it is assumed to be safe to underestimate how constant something is.

+
+## Installation
+
+    npm install constantinople
+
+## Usage
+
+```js
+var isConstant = require('constantinople')
+
+if (isConstant('"foo" + 5')) {
+  console.dir(isConstant.toConstant('"foo" + 5'))
+}
+```
+
+## API
+
+### isConstant(src)
+
+Returns `true` if `src` evaluates to a constant, `false` otherwise.  It will also return `false` if there is a syntax error, which makes it safe to use on potentially ES6 code.
+
+### toConstant(src)
+
+Returns the value resulting from evaluating `src`.  This method throws an error if the expression is not constant.  e.g. `toConstant("Math.random()")` would throw an error.

+UglifyJS 2
+==========
+[![Build Status](https://travis-ci.org/mishoo/UglifyJS2.png)](https://travis-ci.org/mishoo/UglifyJS2)
+
+UglifyJS is a JavaScript parser, minifier, compressor or beautifier toolkit.
+
+This page documents the command line utility.  For
+[API and internals documentation see my website](http://lisperator.net/uglifyjs/).
+There's also an
+[in-browser online demo](http://lisperator.net/uglifyjs/#demo) (for Firefox,
+Chrome and probably Safari).
+
+Install
+-------
+
+First make sure you have installed the latest version of [node.js](http://nodejs.org/)
+(You may need to restart your computer after this step).
+
+From NPM for use as a command line app:
+
+    npm install uglify-js -g
+
+From NPM for programmatic use:
+
+    npm install uglify-js
+
+From Git:
+
+    git clone git://github.com/mishoo/UglifyJS2.git
+    cd UglifyJS2
+    npm link .
+
+Usage
+-----
+
+    uglifyjs [input files] [options]
+
+UglifyJS2 can take multiple input files.  It's recommended that you pass the
+input files first, then pass the options.  UglifyJS will parse input files
+in sequence and apply any compression options.  The files are parsed in the
+same global scope, that is, a reference from a file to some
+variable/function declared in another file will be matched properly.
+
+If you want to read from STDIN instead, pass a single dash instead of input
+files.
+
+The available options are:
+
+```
+  --source-map       Specify an output file where to generate source map.
+                                                                        [string]
+  --source-map-root  The path to the original source to be included in the
+                     source map.                                        [string]
+  --source-map-url   The path to the source map to be added in //#
+                     sourceMappingURL.  Defaults to the value passed with
+                     --source-map.                                      [string]
+  --in-source-map    Input source map, useful if you're compressing JS that was
+                     generated from some other original code.
+  --screw-ie8        Pass this flag if you don't care about full compliance
+                     with Internet Explorer 6-8 quirks (by default UglifyJS
+                     will try to be IE-proof).                         [boolean]
+  --expr             Parse a single expression, rather than a program (for
+                     parsing JSON)                                     [boolean]
+  -p, --prefix       Skip prefix for original filenames that appear in source
+                     maps. For example -p 3 will drop 3 directories from file
+                     names and ensure they are relative paths. You can also
+                     specify -p relative, which will make UglifyJS figure out
+                     itself the relative paths between original sources, the
+                     source map and the output file.                    [string]
+  -o, --output       Output file (default STDOUT).
+  -b, --beautify     Beautify output/specify output options.            [string]
+  -m, --mangle       Mangle names/pass mangler options.                 [string]
+  -r, --reserved     Reserved names to exclude from mangling.
+  -c, --compress     Enable compressor/pass compressor options. Pass options
+                     like -c hoist_vars=false,if_return=false. Use -c with no
+                     argument to use the default compression options.   [string]
+  -d, --define       Global definitions                                 [string]
+  -e, --enclose      Embed everything in a big function, with a configurable
+                     parameter/argument list.                           [string]
+  --comments         Preserve copyright comments in the output. By default this
+                     works like Google Closure, keeping JSDoc-style comments
+                     that contain "@license" or "@preserve". You can optionally
+                     pass one of the following arguments to this flag:
+                     - "all" to keep all comments
+                     - a valid JS regexp (needs to start with a slash) to keep
+                     only comments that match.
+                     Note that currently not *all* comments can be kept when
+                     compression is on, because of dead code removal or
+                     cascading statements into sequences.               [string]
+  --preamble         Preamble to prepend to the output.  You can use this to
+                     insert a comment, for example for licensing information.
+                     This will not be parsed, but the source map will adjust
+                     for its presence.
+  --stats            Display operations run time on STDERR.            [boolean]
+  --acorn            Use Acorn for parsing.                            [boolean]
+  --spidermonkey     Assume input files are SpiderMonkey AST format (as JSON).
+                                                                       [boolean]
+  --self             Build itself (UglifyJS2) as a library (implies
+                     --wrap=UglifyJS --export-all)                     [boolean]
+  --wrap             Embed everything in a big function, making the “exports”
+                     and “global” variables available. You need to pass an
+                     argument to this option to specify the name that your
+                     module will take when included in, say, a browser.
+                                                                        [string]
+  --export-all       Only used when --wrap, this tells UglifyJS to add code to
+                     automatically export all globals.                 [boolean]
+  --lint             Display some scope warnings                       [boolean]
+  -v, --verbose      Verbose                                           [boolean]
+  -V, --version      Print version number and exit.                    [boolean]
+```
+
+Specify `--output` (`-o`) to declare the output file.  Otherwise the output
+goes to STDOUT.
+
+## Source map options
+
+UglifyJS2 can generate a source map file, which is highly useful for
+debugging your compressed JavaScript.  To get a source map, pass
+`--source-map output.js.map` (full path to the file where you want the
+source map dumped).
+
+Additionally you might need `--source-map-root` to pass the URL where the
+original files can be found.  In case you are passing full paths to input
+files to UglifyJS, you can use `--prefix` (`-p`) to specify the number of
+directories to drop from the path prefix when declaring files in the source
+map.
+
+For example:
+
+    uglifyjs /home/doe/work/foo/src/js/file1.js \
+             /home/doe/work/foo/src/js/file2.js \
+             -o foo.min.js \
+             --source-map foo.min.js.map \
+             --source-map-root http://foo.com/src \
+             -p 5 -c -m
+
+The above will compress and mangle `file1.js` and `file2.js`, will drop the
+output in `foo.min.js` and the source map in `foo.min.js.map`.  The source
+mapping will refer to `http://foo.com/src/js/file1.js` and
+`http://foo.com/src/js/file2.js` (in fact it will list `http://foo.com/src`
+as the source map root, and the original files as `js/file1.js` and
+`js/file2.js`).
+
+### Composed source map
+
+When you're compressing JS code that was output by a compiler such as
+CoffeeScript, mapping to the JS code won't be too helpful.  Instead, you'd
+like to map back to the original code (i.e. CoffeeScript).  UglifyJS has an
+option to take an input source map.  Assuming you have a mapping from
+CoffeeScript → compiled JS, UglifyJS can generate a map from CoffeeScript →
+compressed JS by mapping every token in the compiled JS to its original
+location.
+
+To use this feature you need to pass `--in-source-map
+/path/to/input/source.map`.  Normally the input source map should also point
+to the file containing the generated JS, so if that's correct you can omit
+input files from the command line.
+
+## Mangler options
+
+To enable the mangler you need to pass `--mangle` (`-m`).  The following
+(comma-separated) options are supported:
+
+- `sort` — to assign shorter names to most frequently used variables.  This
+  saves a few hundred bytes on jQuery before gzip, but the output is
+  _bigger_ after gzip (and seems to happen for other libraries I tried it
+  on) therefore it's not enabled by default.
+
+- `toplevel` — mangle names declared in the toplevel scope (disabled by
+  default).
+
+- `eval` — mangle names visible in scopes where `eval` or `when` are used
+  (disabled by default).
+
+When mangling is enabled but you want to prevent certain names from being
+mangled, you can declare those names with `--reserved` (`-r`) — pass a
+comma-separated list of names.  For example:
+
+    uglifyjs ... -m -r '$,require,exports'
+
+to prevent the `require`, `exports` and `$` names from being changed.
+
+## Compressor options
+
+You need to pass `--compress` (`-c`) to enable the compressor.  Optionally
+you can pass a comma-separated list of options.  Options are in the form
+`foo=bar`, or just `foo` (the latter implies a boolean option that you want
+to set `true`; it's effectively a shortcut for `foo=true`).
+
+- `sequences` -- join consecutive simple statements using the comma operator
+
+- `properties` -- rewrite property access using the dot notation, for
+  example `foo["bar"] → foo.bar`
+
+- `dead_code` -- remove unreachable code
+
+- `drop_debugger` -- remove `debugger;` statements
+
+- `unsafe` (default: false) -- apply "unsafe" transformations (discussion below)
+
+- `conditionals` -- apply optimizations for `if`-s and conditional
+  expressions
+
+- `comparisons` -- apply certain optimizations to binary nodes, for example:
+  `!(a <= b) → a > b` (only when `unsafe`), attempts to negate binary nodes,
+  e.g. `a = !b && !c && !d && !e → a=!(b||c||d||e)` etc.
+
+- `evaluate` -- attempt to evaluate constant expressions
+
+- `booleans` -- various optimizations for boolean context, for example `!!a
+  ? b : c → a ? b : c`
+
+- `loops` -- optimizations for `do`, `while` and `for` loops when we can
+  statically determine the condition
+
+- `unused` -- drop unreferenced functions and variables
+
+- `hoist_funs` -- hoist function declarations
+
+- `hoist_vars` (default: false) -- hoist `var` declarations (this is `false`
+  by default because it seems to increase the size of the output in general)
+
+- `if_return` -- optimizations for if/return and if/continue
+
+- `join_vars` -- join consecutive `var` statements
+
+- `cascade` -- small optimization for sequences, transform `x, x` into `x`
+  and `x = something(), x` into `x = something()`
+
+- `warnings` -- display warnings when dropping unreachable code or unused
+  declarations etc.
+
+- `negate_iife` -- negate "Immediately-Called Function Expressions"
+  where the return value is discarded, to avoid the parens that the
+  code generator would insert.
+
+- `pure_getters` -- the default is `false`.  If you pass `true` for
+  this, UglifyJS will assume that object property access
+  (e.g. `foo.bar` or `foo["bar"]`) doesn't have any side effects.
+
+- `pure_funcs` -- default `null`.  You can pass an array of names and
+  UglifyJS will assume that those functions do not produce side
+  effects.  DANGER: will not check if the name is redefined in scope.
+  An example case here, for instance `var q = Math.floor(a/b)`.  If
+  variable `q` is not used elsewhere, UglifyJS will drop it, but will
+  still keep the `Math.floor(a/b)`, not knowing what it does.  You can
+  pass `pure_funcs: [ 'Math.floor' ]` to let it know that this
+  function won't produce any side effect, in which case the whole
+  statement would get discarded.  The current implementation adds some
+  overhead (compression will be slower).
+
+- `drop_console` -- default `false`.  Pass `true` to discard calls to
+  `console.*` functions.
+
+### The `unsafe` option
+
+It enables some transformations that *might* break code logic in certain
+contrived cases, but should be fine for most code.  You might want to try it
+on your own code, it should reduce the minified size.  Here's what happens
+when this flag is on:
+
+- `new Array(1, 2, 3)` or `Array(1, 2, 3)` → `[1, 2, 3 ]`
+- `new Object()` → `{}`
+- `String(exp)` or `exp.toString()` → `"" + exp`
+- `new Object/RegExp/Function/Error/Array (...)` → we discard the `new`
+- `typeof foo == "undefined"` → `foo === void 0`
+- `void 0` → `undefined` (if there is a variable named "undefined" in
+  scope; we do it because the variable name will be mangled, typically
+  reduced to a single character).
+
+### Conditional compilation
+
+You can use the `--define` (`-d`) switch in order to declare global
+variables that UglifyJS will assume to be constants (unless defined in
+scope).  For example if you pass `--define DEBUG=false` then, coupled with
+dead code removal UglifyJS will discard the following from the output:
+```javascript
+if (DEBUG) {
+	console.log("debug stuff");
+}
+```
+
+UglifyJS will warn about the condition being always false and about dropping
+unreachable code; for now there is no option to turn off only this specific
+warning, you can pass `warnings=false` to turn off *all* warnings.
+
+Another way of doing that is to declare your globals as constants in a
+separate file and include it into the build.  For example you can have a
+`build/defines.js` file with the following:
+```javascript
+const DEBUG = false;
+const PRODUCTION = true;
+// etc.
+```
+
+and build your code like this:
+
+    uglifyjs build/defines.js js/foo.js js/bar.js... -c
+
+UglifyJS will notice the constants and, since they cannot be altered, it
+will evaluate references to them to the value itself and drop unreachable
+code as usual.  The possible downside of this approach is that the build
+will contain the `const` declarations.
+
+<a name="codegen-options"></a>
+## Beautifier options
+
+The code generator tries to output shortest code possible by default.  In
+case you want beautified output, pass `--beautify` (`-b`).  Optionally you
+can pass additional arguments that control the code output:
+
+- `beautify` (default `true`) -- whether to actually beautify the output.
+  Passing `-b` will set this to true, but you might need to pass `-b` even
+  when you want to generate minified code, in order to specify additional
+  arguments, so you can use `-b beautify=false` to override it.
+- `indent-level` (default 4)
+- `indent-start` (default 0) -- prefix all lines by that many spaces
+- `quote-keys` (default `false`) -- pass `true` to quote all keys in literal
+  objects
+- `space-colon` (default `true`) -- insert a space after the colon signs
+- `ascii-only` (default `false`) -- escape Unicode characters in strings and
+  regexps
+- `inline-script` (default `false`) -- escape the slash in occurrences of
+  `</script` in strings
+- `width` (default 80) -- only takes effect when beautification is on, this
+  specifies an (orientative) line width that the beautifier will try to
+  obey.  It refers to the width of the line text (excluding indentation).
+  It doesn't work very well currently, but it does make the code generated
+  by UglifyJS more readable.
+- `max-line-len` (default 32000) -- maximum line length (for uglified code)
+- `bracketize` (default `false`) -- always insert brackets in `if`, `for`,
+  `do`, `while` or `with` statements, even if their body is a single
+  statement.
+- `semicolons` (default `true`) -- separate statements with semicolons.  If
+  you pass `false` then whenever possible we will use a newline instead of a
+  semicolon, leading to more readable output of uglified code (size before
+  gzip could be smaller; size after gzip insignificantly larger).
+- `preamble` (default `null`) -- when passed it must be a string and
+  it will be prepended to the output literally.  The source map will
+  adjust for this text.  Can be used to insert a comment containing
+  licensing information, for example.
+
+### Keeping copyright notices or other comments
+
+You can pass `--comments` to retain certain comments in the output.  By
+default it will keep JSDoc-style comments that contain "@preserve",
+"@license" or "@cc_on" (conditional compilation for IE).  You can pass
+`--comments all` to keep all the comments, or a valid JavaScript regexp to
+keep only comments that match this regexp.  For example `--comments
+'/foo|bar/'` will keep only comments that contain "foo" or "bar".
+
+Note, however, that there might be situations where comments are lost.  For
+example:
+```javascript
+function f() {
+	/** @preserve Foo Bar */
+	function g() {
+	  // this function is never called
+	}
+	return something();
+}
+```
+
+Even though it has "@preserve", the comment will be lost because the inner
+function `g` (which is the AST node to which the comment is attached to) is
+discarded by the compressor as not referenced.
+
+The safest comments where to place copyright information (or other info that
+needs to be kept in the output) are comments attached to toplevel nodes.
+
+## Support for the SpiderMonkey AST
+
+UglifyJS2 has its own abstract syntax tree format; for
+[practical reasons](http://lisperator.net/blog/uglifyjs-why-not-switching-to-spidermonkey-ast/)
+we can't easily change to using the SpiderMonkey AST internally.  However,
+UglifyJS now has a converter which can import a SpiderMonkey AST.
+
+For example [Acorn][acorn] is a super-fast parser that produces a
+SpiderMonkey AST.  It has a small CLI utility that parses one file and dumps
+the AST in JSON on the standard output.  To use UglifyJS to mangle and
+compress that:
+
+    acorn file.js | uglifyjs --spidermonkey -m -c
+
+The `--spidermonkey` option tells UglifyJS that all input files are not
+JavaScript, but JS code described in SpiderMonkey AST in JSON.  Therefore we
+don't use our own parser in this case, but just transform that AST into our
+internal AST.
+
+### Use Acorn for parsing
+
+More for fun, I added the `--acorn` option which will use Acorn to do all
+the parsing.  If you pass this option, UglifyJS will `require("acorn")`.
+
+Acorn is really fast (e.g. 250ms instead of 380ms on some 650K code), but
+converting the SpiderMonkey tree that Acorn produces takes another 150ms so
+in total it's a bit more than just using UglifyJS's own parser.
+
+API Reference
+-------------
+
+Assuming installation via NPM, you can load UglifyJS in your application
+like this:
+```javascript
+var UglifyJS = require("uglify-js");
+```
+
+It exports a lot of names, but I'll discuss here the basics that are needed
+for parsing, mangling and compressing a piece of code.  The sequence is (1)
+parse, (2) compress, (3) mangle, (4) generate output code.
+
+### The simple way
+
+There's a single toplevel function which combines all the steps.  If you
+don't need additional customization, you might want to go with `minify`.
+Example:
+```javascript
+var result = UglifyJS.minify("/path/to/file.js");
+console.log(result.code); // minified output
+// if you need to pass code instead of file name
+var result = UglifyJS.minify("var b = function () {};", {fromString: true});
+```
+
+You can also compress multiple files:
+```javascript
+var result = UglifyJS.minify([ "file1.js", "file2.js", "file3.js" ]);
+console.log(result.code);
+```
+
+To generate a source map:
+```javascript
+var result = UglifyJS.minify([ "file1.js", "file2.js", "file3.js" ], {
+	outSourceMap: "out.js.map"
+});
+console.log(result.code); // minified output
+console.log(result.map);
+```
+
+Note that the source map is not saved in a file, it's just returned in
+`result.map`.  The value passed for `outSourceMap` is only used to set the
+`file` attribute in the source map (see [the spec][sm-spec]).
+
+You can also specify sourceRoot property to be included in source map:
+```javascript
+var result = UglifyJS.minify([ "file1.js", "file2.js", "file3.js" ], {
+	outSourceMap: "out.js.map",
+	sourceRoot: "http://example.com/src"
+});
+```
+
+If you're compressing compiled JavaScript and have a source map for it, you
+can use the `inSourceMap` argument:
+```javascript
+var result = UglifyJS.minify("compiled.js", {
+	inSourceMap: "compiled.js.map",
+	outSourceMap: "minified.js.map"
+});
+// same as before, it returns `code` and `map`
+```
+
+The `inSourceMap` is only used if you also request `outSourceMap` (it makes
+no sense otherwise).
+
+Other options:
+
+- `warnings` (default `false`) — pass `true` to display compressor warnings.
+
+- `fromString` (default `false`) — if you pass `true` then you can pass
+  JavaScript source code, rather than file names.
+
+- `mangle` — pass `false` to skip mangling names.
+
+- `output` (default `null`) — pass an object if you wish to specify
+  additional [output options][codegen].  The defaults are optimized
+  for best compression.
+
+- `compress` (default `{}`) — pass `false` to skip compressing entirely.
+  Pass an object to specify custom [compressor options][compressor].
+
+We could add more options to `UglifyJS.minify` — if you need additional
+functionality please suggest!
+
+### The hard way
+
+Following there's more detailed API info, in case the `minify` function is
+too simple for your needs.
+
+#### The parser
+```javascript
+var toplevel_ast = UglifyJS.parse(code, options);
+```
+
+`options` is optional and if present it must be an object.  The following
+properties are available:
+
+- `strict` — disable automatic semicolon insertion and support for trailing
+  comma in arrays and objects
+- `filename` — the name of the file where this code is coming from
+- `toplevel` — a `toplevel` node (as returned by a previous invocation of
+  `parse`)
+
+The last two options are useful when you'd like to minify multiple files and
+get a single file as the output and a proper source map.  Our CLI tool does
+something like this:
+```javascript
+var toplevel = null;
+files.forEach(function(file){
+	var code = fs.readFileSync(file, "utf8");
+	toplevel = UglifyJS.parse(code, {
+		filename: file,
+		toplevel: toplevel
+	});
+});
+```
+
+After this, we have in `toplevel` a big AST containing all our files, with
+each token having proper information about where it came from.
+
+#### Scope information
+
+UglifyJS contains a scope analyzer that you need to call manually before
+compressing or mangling.  Basically it augments various nodes in the AST
+with information about where is a name defined, how many times is a name
+referenced, if it is a global or not, if a function is using `eval` or the
+`with` statement etc.  I will discuss this some place else, for now what's
+important to know is that you need to call the following before doing
+anything with the tree:
+```javascript
+toplevel.figure_out_scope()
+```
+
+#### Compression
+
+Like this:
+```javascript
+var compressor = UglifyJS.Compressor(options);
+var compressed_ast = toplevel.transform(compressor);
+```
+
+The `options` can be missing.  Available options are discussed above in
+“Compressor options”.  Defaults should lead to best compression in most
+scripts.
+
+The compressor is destructive, so don't rely that `toplevel` remains the
+original tree.
+
+#### Mangling
+
+After compression it is a good idea to call again `figure_out_scope` (since
+the compressor might drop unused variables / unreachable code and this might
+change the number of identifiers or their position).  Optionally, you can
+call a trick that helps after Gzip (counting character frequency in
+non-mangleable words).  Example:
+```javascript
+compressed_ast.figure_out_scope();
+compressed_ast.compute_char_frequency();
+compressed_ast.mangle_names();
+```
+
+#### Generating output
+
+AST nodes have a `print` method that takes an output stream.  Essentially,
+to generate code you do this:
+```javascript
+var stream = UglifyJS.OutputStream(options);
+compressed_ast.print(stream);
+var code = stream.toString(); // this is your minified code
+```
+
+or, for a shortcut you can do:
+```javascript
+var code = compressed_ast.print_to_string(options);
+```
+
+As usual, `options` is optional.  The output stream accepts a lot of otions,
+most of them documented above in section “Beautifier options”.  The two
+which we care about here are `source_map` and `comments`.
+
+#### Keeping comments in the output
+
+In order to keep certain comments in the output you need to pass the
+`comments` option.  Pass a RegExp or a function.  If you pass a RegExp, only
+those comments whose body matches the regexp will be kept.  Note that body
+means without the initial `//` or `/*`.  If you pass a function, it will be
+called for every comment in the tree and will receive two arguments: the
+node that the comment is attached to, and the comment token itself.
+
+The comment token has these properties:
+
+- `type`: "comment1" for single-line comments or "comment2" for multi-line
+  comments
+- `value`: the comment body
+- `pos` and `endpos`: the start/end positions (zero-based indexes) in the
+  original code where this comment appears
+- `line` and `col`: the line and column where this comment appears in the
+  original code
+- `file` — the file name of the original file
+- `nlb` — true if there was a newline before this comment in the original
+  code, or if this comment contains a newline.
+
+Your function should return `true` to keep the comment, or a falsy value
+otherwise.
+
+#### Generating a source mapping
+
+You need to pass the `source_map` argument when calling `print`.  It needs
+to be a `SourceMap` object (which is a thin wrapper on top of the
+[source-map][source-map] library).
+
+Example:
+```javascript
+var source_map = UglifyJS.SourceMap(source_map_options);
+var stream = UglifyJS.OutputStream({
+	...
+	source_map: source_map
+});
+compressed_ast.print(stream);
+
+var code = stream.toString();
+var map = source_map.toString(); // json output for your source map
+```
+
+The `source_map_options` (optional) can contain the following properties:
+
+- `file`: the name of the JavaScript output file that this mapping refers to
+- `root`: the `sourceRoot` property (see the [spec][sm-spec])
+- `orig`: the "original source map", handy when you compress generated JS
+  and want to map the minified output back to the original code where it
+  came from.  It can be simply a string in JSON, or a JSON object containing
+  the original source map.

+
+methods
+=======
+
+var wrap = require('wordwrap');
+
+wrap(stop), wrap(start, stop, params={mode:"soft"})
+---------------------------------------------------
+
+Returns a function that takes a string and returns a new string.
+
+Pad out lines with spaces out to column `start` and then wrap until column
+`stop`. If a word is longer than `stop - start` characters it will overflow.
+
+In "soft" mode, split chunks by `/(\S+\s+/` and don't break up chunks which are
+longer than `stop - start`, in "hard" mode, split chunks with `/\b/` and break
+up chunks longer than `stop - start`.
+
+wrap.hard(start, stop)
+----------------------
+
+Like `wrap()` but with `params.mode = "hard"`.

+In Praise of Idleness
+
+By Bertrand Russell
+
+[1932]
+
+Like most of my generation, I was brought up on the saying: 'Satan finds some mischief for idle hands to do.' Being a highly virtuous child, I believed all that I was told, and acquired a conscience which has kept me working hard down to the present moment. But although my conscience has controlled my actions, my opinions have undergone a revolution. I think that there is far too much work done in the world, that immense harm is caused by the belief that work is virtuous, and that what needs to be preached in modern industrial countries is quite different from what always has been preached. Everyone knows the story of the traveler in Naples who saw twelve beggars lying in the sun (it was before the days of Mussolini), and offered a lira to the laziest of them. Eleven of them jumped up to claim it, so he gave it to the twelfth. this traveler was on the right lines. But in countries which do not enjoy Mediterranean sunshine idleness is more difficult, and a great public propaganda will be required to inaugurate it. I hope that, after reading the following pages, the leaders of the YMCA will start a campaign to induce good young men to do nothing. If so, I shall not have lived in vain.
+
+Before advancing my own arguments for laziness, I must dispose of one which I cannot accept. Whenever a person who already has enough to live on proposes to engage in some everyday kind of job, such as school-teaching or typing, he or she is told that such conduct takes the bread out of other people's mouths, and is therefore wicked. If this argument were valid, it would only be necessary for us all to be idle in order that we should all have our mouths full of bread. What people who say such things forget is that what a man earns he usually spends, and in spending he gives employment. As long as a man spends his income, he puts just as much bread into people's mouths in spending as he takes out of other people's mouths in earning. The real villain, from this point of view, is the man who saves. If he merely puts his savings in a stocking, like the proverbial French peasant, it is obvious that they do not give employment. If he invests his savings, the matter is less obvious, and different cases arise.
+
+One of the commonest things to do with savings is to lend them to some Government. In view of the fact that the bulk of the public expenditure of most civilized Governments consists in payment for past wars or preparation for future wars, the man who lends his money to a Government is in the same position as the bad men in Shakespeare who hire murderers. The net result of the man's economical habits is to increase the armed forces of the State to which he lends his savings. Obviously it would be better if he spent the money, even if he spent it in drink or gambling.
+
+But, I shall be told, the case is quite different when savings are invested in industrial enterprises. When such enterprises succeed, and produce something useful, this may be conceded. In these days, however, no one will deny that most enterprises fail. That means that a large amount of human labor, which might have been devoted to producing something that could be enjoyed, was expended on producing machines which, when produced, lay idle and did no good to anyone. The man who invests his savings in a concern that goes bankrupt is therefore injuring others as well as himself. If he spent his money, say, in giving parties for his friends, they (we may hope) would get pleasure, and so would all those upon whom he spent money, such as the butcher, the baker, and the bootlegger. But if he spends it (let us say) upon laying down rails for surface card in some place where surface cars turn out not to be wanted, he has diverted a mass of labor into channels where it gives pleasure to no one. Nevertheless, when he becomes poor through failure of his investment he will be regarded as a victim of undeserved misfortune, whereas the gay spendthrift, who has spent his money philanthropically, will be despised as a fool and a frivolous person.
+
+All this is only preliminary. I want to say, in all seriousness, that a great deal of harm is being done in the modern world by belief in the virtuousness of work, and that the road to happiness and prosperity lies in an organized diminution of work.
+
+First of all: what is work? Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so. The first kind is unpleasant and ill paid; the second is pleasant and highly paid. The second kind is capable of indefinite extension: there are not only those who give orders, but those who give advice as to what orders should be given. Usually two opposite kinds of advice are given simultaneously by two organized bodies of men; this is called politics. The skill required for this kind of work is not knowledge of the subjects as to which advice is given, but knowledge of the art of persuasive speaking and writing, i.e. of advertising.
+
+Throughout Europe, though not in America, there is a third class of men, more respected than either of the classes of workers. There are men who, through ownership of land, are able to make others pay for the privilege of being allowed to exist and to work. These landowners are idle, and I might therefore be expected to praise them. Unfortunately, their idleness is only rendered possible by the industry of others; indeed their desire for comfortable idleness is historically the source of the whole gospel of work. The last thing they have ever wished is that others should follow their example.
+
+From the beginning of civilization until the Industrial Revolution, a man could, as a rule, produce by hard work little more than was required for the subsistence of himself and his family, although his wife worked at least as hard as he did, and his children added their labor as soon as they were old enough to do so. The small surplus above bare necessaries was not left to those who produced it, but was appropriated by warriors and priests. In times of famine there was no surplus; the warriors and priests, however, still secured as much as at other times, with the result that many of the workers died of hunger. This system persisted in Russia until 1917 [1], and still persists in the East; in England, in spite of the Industrial Revolution, it remained in full force throughout the Napoleonic wars, and until a hundred years ago, when the new class of manufacturers acquired power. In America, the system came to an end with the Revolution, except in the South, where it persisted until the Civil War. A system which lasted so long and ended so recently has naturally left a profound impress upon men's thoughts and opinions. Much that we take for granted about the desirability of work is derived from this system, and, being pre-industrial, is not adapted to the modern world. Modern technique has made it possible for leisure, within limits, to be not the prerogative of small privileged classes, but a right evenly distributed throughout the community. The morality of work is the morality of slaves, and the modern world has no need of slavery.
+
+It is obvious that, in primitive communities, peasants, left to themselves, would not have parted with the slender surplus upon which the warriors and priests subsisted, but would have either produced less or consumed more. At first, sheer force compelled them to produce and part with the surplus. Gradually, however, it was found possible to induce many of them to accept an ethic according to which it was their duty to work hard, although part of their work went to support others in idleness. By this means the amount of compulsion required was lessened, and the expenses of government were diminished. To this day, 99 per cent of British wage-earners would be genuinely shocked if it were proposed that the King should not have a larger income than a working man. The conception of duty, speaking historically, has been a means used by the holders of power to induce others to live for the interests of their masters rather than for their own. Of course the holders of power conceal this fact from themselves by managing to believe that their interests are identical with the larger interests of humanity. Sometimes this is true; Athenian slave-owners, for instance, employed part of their leisure in making a permanent contribution to civilization which would have been impossible under a just economic system. Leisure is essential to civilization, and in former times leisure for the few was only rendered possible by the labors of the many. But their labors were valuable, not because work is good, but because leisure is good. And with modern technique it would be possible to distribute leisure justly without injury to civilization.
+
+Modern technique has made it possible to diminish enormously the amount of labor required to secure the necessaries of life for everyone. This was made obvious during the war. At that time all the men in the armed forces, and all the men and women engaged in the production of munitions, all the men and women engaged in spying, war propaganda, or Government offices connected with the war, were withdrawn from productive occupations. In spite of this, the general level of well-being among unskilled wage-earners on the side of the Allies was higher than before or since. The significance of this fact was concealed by finance: borrowing made it appear as if the future was nourishing the present. But that, of course, would have been impossible; a man cannot eat a loaf of bread that does not yet exist. The war showed conclusively that, by the scientific organization of production, it is possible to keep modern populations in fair comfort on a small part of the working capacity of the modern world. If, at the end of the war, the scientific organization, which had been created in order to liberate men for fighting and munition work, had been preserved, and the hours of the week had been cut down to four, all would have been well. Instead of that the old chaos was restored, those whose work was demanded were made to work long hours, and the rest were left to starve as unemployed. Why? Because work is a duty, and a man should not receive wages in proportion to what he has produced, but in proportion to his virtue as exemplified by his industry.
+
+This is the morality of the Slave State, applied in circumstances totally unlike those in which it arose. No wonder the result has been disastrous. Let us take an illustration. Suppose that, at a given moment, a certain number of people are engaged in the manufacture of pins. They make as many pins as the world needs, working (say) eight hours a day. Someone makes an invention by which the same number of men can make twice as many pins: pins are already so cheap that hardly any more will be bought at a lower price. In a sensible world, everybody concerned in the manufacturing of pins would take to working four hours instead of eight, and everything else would go on as before. But in the actual world this would be thought demoralizing. The men still work eight hours, there are too many pins, some employers go bankrupt, and half the men previously concerned in making pins are thrown out of work. There is, in the end, just as much leisure as on the other plan, but half the men are totally idle while half are still overworked. In this way, it is insured that the unavoidable leisure shall cause misery all round instead of being a universal source of happiness. Can anything more insane be imagined?
+
+The idea that the poor should have leisure has always been shocking to the rich. In England, in the early nineteenth century, fifteen hours was the ordinary day's work for a man; children sometimes did as much, and very commonly did twelve hours a day. When meddlesome busybodies suggested that perhaps these hours were rather long, they were told that work kept adults from drink and children from mischief. When I was a child, shortly after urban working men had acquired the vote, certain public holidays were established by law, to the great indignation of the upper classes. I remember hearing an old Duchess say: 'What do the poor want with holidays? They ought to work.' People nowadays are less frank, but the sentiment persists, and is the source of much of our economic confusion.
+
+Let us, for a moment, consider the ethics of work frankly, without superstition. Every human being, of necessity, consumes, in the course of his life, a certain amount of the produce of human labor. Assuming, as we may, that labor is on the whole disagreeable, it is unjust that a man should consume more than he produces. Of course he may provide services rather than commodities, like a medical man, for example; but he should provide something in return for his board and lodging. to this extent, the duty of work must be admitted, but to this extent only.
+
+I shall not dwell upon the fact that, in all modern societies outside the USSR, many people escape even this minimum amount of work, namely all those who inherit money and all those who marry money. I do not think the fact that these people are allowed to be idle is nearly so harmful as the fact that wage-earners are expected to overwork or starve.
+
+If the ordinary wage-earner worked four hours a day, there would be enough for everybody and no unemployment -- assuming a certain very moderate amount of sensible organization. This idea shocks the well-to-do, because they are convinced that the poor would not know how to use so much leisure. In America men often work long hours even when they are well off; such men, naturally, are indignant at the idea of leisure for wage-earners, except as the grim punishment of unemployment; in fact, they dislike leisure even for their sons. Oddly enough, while they wish their sons to work so hard as to have no time to be civilized, they do not mind their wives and daughters having no work at all. the snobbish admiration of uselessness, which, in an aristocratic society, extends to both sexes, is, under a plutocracy, confined to women; this, however, does not make it any more in agreement with common sense.
+
+The wise use of leisure, it must be conceded, is a product of civilization and education. A man who has worked long hours all his life will become bored if he becomes suddenly idle. But without a considerable amount of leisure a man is cut off from many of the best things. There is no longer any reason why the bulk of the population should suffer this deprivation; only a foolish asceticism, usually vicarious, makes us continue to insist on work in excessive quantities now that the need no longer exists.
+
+In the new creed which controls the government of Russia, while there is much that is very different from the traditional teaching of the West, there are some things that are quite unchanged. The attitude of the governing classes, and especially of those who conduct educational propaganda, on the subject of the dignity of labor, is almost exactly that which the governing classes of the world have always preached to what were called the 'honest poor'. Industry, sobriety, willingness to work long hours for distant advantages, even submissiveness to authority, all these reappear; moreover authority still represents the will of the Ruler of the Universe, Who, however, is now called by a new name, Dialectical Materialism.
+
+The victory of the proletariat in Russia has some points in common with the victory of the feminists in some other countries. For ages, men had conceded the superior saintliness of women, and had consoled women for their inferiority by maintaining that saintliness is more desirable than power. At last the feminists decided that they would have both, since the pioneers among them believed all that the men had told them about the desirability of virtue, but not what they had told them about the worthlessness of political power. A similar thing has happened in Russia as regards manual work. For ages, the rich and their sycophants have written in praise of 'honest toil', have praised the simple life, have professed a religion which teaches that the poor are much more likely to go to heaven than the rich, and in general have tried to make manual workers believe that there is some special nobility about altering the position of matter in space, just as men tried to make women believe that they derived some special nobility from their sexual enslavement. In Russia, all this teaching about the excellence of manual work has been taken seriously, with the result that the manual worker is more honored than anyone else. What are, in essence, revivalist appeals are made, but not for the old purposes: they are made to secure shock workers for special tasks. Manual work is the ideal which is held before the young, and is the basis of all ethical teaching.
+
+For the present, possibly, this is all to the good. A large country, full of natural resources, awaits development, and has has to be developed with very little use of credit. In these circumstances, hard work is necessary, and is likely to bring a great reward. But what will happen when the point has been reached where everybody could be comfortable without working long hours?
+
+In the West, we have various ways of dealing with this problem. We have no attempt at economic justice, so that a large proportion of the total produce goes to a small minority of the population, many of whom do no work at all. Owing to the absence of any central control over production, we produce hosts of things that are not wanted. We keep a large percentage of the working population idle, because we can dispense with their labor by making the others overwork. When all these methods prove inadequate, we have a war: we cause a number of people to manufacture high explosives, and a number of others to explode them, as if we were children who had just discovered fireworks. By a combination of all these devices we manage, though with difficulty, to keep alive the notion that a great deal of severe manual work must be the lot of the average man.
+
+In Russia, owing to more economic justice and central control over production, the problem will have to be differently solved. the rational solution would be, as soon as the necessaries and elementary comforts can be provided for all, to reduce the hours of labor gradually, allowing a popular vote to decide, at each stage, whether more leisure or more goods were to be preferred. But, having taught the supreme virtue of hard work, it is difficult to see how the authorities can aim at a paradise in which there will be much leisure and little work. It seems more likely that they will find continually fresh schemes, by which present leisure is to be sacrificed to future productivity. I read recently of an ingenious plan put forward by Russian engineers, for making the White Sea and the northern coasts of Siberia warm, by putting a dam across the Kara Sea. An admirable project, but liable to postpone proletarian comfort for a generation, while the nobility of toil is being displayed amid the ice-fields and snowstorms of the Arctic Ocean. This sort of thing, if it happens, will be the result of regarding the virtue of hard work as an end in itself, rather than as a means to a state of affairs in which it is no longer needed.
+
+The fact is that moving matter about, while a certain amount of it is necessary to our existence, is emphatically not one of the ends of human life. If it were, we should have to consider every navvy superior to Shakespeare. We have been misled in this matter by two causes. One is the necessity of keeping the poor contented, which has led the rich, for thousands of years, to preach the dignity of labor, while taking care themselves to remain undignified in this respect. The other is the new pleasure in mechanism, which makes us delight in the astonishingly clever changes that we can produce on the earth's surface. Neither of these motives makes any great appeal to the actual worker. If you ask him what he thinks the best part of his life, he is not likely to say: 'I enjoy manual work because it makes me feel that I am fulfilling man's noblest task, and because I like to think how much man can transform his planet. It is true that my body demands periods of rest, which I have to fill in as best I may, but I am never so happy as when the morning comes and I can return to the toil from which my contentment springs.' I have never heard working men say this sort of thing. They consider work, as it should be considered, a necessary means to a livelihood, and it is from their leisure that they derive whatever happiness they may enjoy.
+
+It will be said that, while a little leisure is pleasant, men would not know how to fill their days if they had only four hours of work out of the twenty-four. In so far as this is true in the modern world, it is a condemnation of our civilization; it would not have been true at any earlier period. There was formerly a capacity for light-heartedness and play which has been to some extent inhibited by the cult of efficiency. The modern man thinks that everything ought to be done for the sake of something else, and never for its own sake. Serious-minded persons, for example, are continually condemning the habit of going to the cinema, and telling us that it leads the young into crime. But all the work that goes to producing a cinema is respectable, because it is work, and because it brings a money profit. The notion that the desirable activities are those that bring a profit has made everything topsy-turvy. The butcher who provides you with meat and the baker who provides you with bread are praiseworthy, because they are making money; but when you enjoy the food they have provided, you are merely frivolous, unless you eat only to get strength for your work. Broadly speaking, it is held that getting money is good and spending money is bad. Seeing that they are two sides of one transaction, this is absurd; one might as well maintain that keys are good, but keyholes are bad. Whatever merit there may be in the production of goods must be entirely derivative from the advantage to be obtained by consuming them. The individual, in our society, works for profit; but the social purpose of his work lies in the consumption of what he produces. It is this divorce between the individual and the social purpose of production that makes it so difficult for men to think clearly in a world in which profit-making is the incentive to industry. We think too much of production, and too little of consumption. One result is that we attach too little importance to enjoyment and simple happiness, and that we do not judge production by the pleasure that it gives to the consumer.

+When I suggest that working hours should be reduced to four, I am not meaning to imply that all the remaining time should necessarily be spent in pure frivolity. I mean that four hours' work a day should entitle a man to the necessities and elementary comforts of life, and that the rest of his time should be his to use as he might see fit. It is an essential part of any such social system that education should be carried further than it usually is at present, and should aim, in part, at providing tastes which would enable a man to use leisure intelligently. I am not thinking mainly of the sort of things that would be considered 'highbrow'. Peasant dances have died out except in remote rural areas, but the impulses which caused them to be cultivated must still exist in human nature. The pleasures of urban populations have become mainly passive: seeing cinemas, watching football matches, listening to the radio, and so on. This results from the fact that their active energies are fully taken up with work; if they had more leisure, they would again enjoy pleasures in which they took an active part.
+
+In the past, there was a small leisure class and a larger working class. The leisure class enjoyed advantages for which there was no basis in social justice; this necessarily made it oppressive, limited its sympathies, and caused it to invent theories by which to justify its privileges. These facts greatly diminished its excellence, but in spite of this drawback it contributed nearly the whole of what we call civilization. It cultivated the arts and discovered the sciences; it wrote the books, invented the philosophies, and refined social relations. Even the liberation of the oppressed has usually been inaugurated from above. Without the leisure class, mankind would never have emerged from barbarism.
+
+The method of a leisure class without duties was, however, extraordinarily wasteful. None of the members of the class had to be taught to be industrious, and the class as a whole was not exceptionally intelligent. The class might produce one Darwin, but against him had to be set tens of thousands of country gentlemen who never thought of anything more intelligent than fox-hunting and punishing poachers. At present, the universities are supposed to provide, in a more systematic way, what the leisure class provided accidentally and as a by-product. This is a great improvement, but it has certain drawbacks. University life is so different from life in the world at large that men who live in academic milieu tend to be unaware of the preoccupations and problems of ordinary men and women; moreover their ways of expressing themselves are usually such as to rob their opinions of the influence that they ought to have upon the general public. Another disadvantage is that in universities studies are organized, and the man who thinks of some original line of research is likely to be discouraged. Academic institutions, therefore, useful as they are, are not adequate guardians of the interests of civilization in a world where everyone outside their walls is too busy for unutilitarian pursuits.
+
+In a world where no one is compelled to work more than four hours a day, every person possessed of scientific curiosity will be able to indulge it, and every painter will be able to paint without starving, however excellent his pictures may be. Young writers will not be obliged to draw attention to themselves by sensational pot-boilers, with a view to acquiring the economic independence needed for monumental works, for which, when the time at last comes, they will have lost the taste and capacity. Men who, in their professional work, have become interested in some phase of economics or government, will be able to develop their ideas without the academic detachment that makes the work of university economists often seem lacking in reality. Medical men will have the time to learn about the progress of medicine, teachers will not be exasperatedly struggling to teach by routine methods things which they learnt in their youth, which may, in the interval, have been proved to be untrue.
+
+Above all, there will be happiness and joy of life, instead of frayed nerves, weariness, and dyspepsia. The work exacted will be enough to make leisure delightful, but not enough to produce exhaustion. Since men will not be tired in their spare time, they will not demand only such amusements as are passive and vapid. At least one per cent will probably devote the time not spent in professional work to pursuits of some public importance, and, since they will not depend upon these pursuits for their livelihood, their originality will be unhampered, and there will be no need to conform to the standards set by elderly pundits. But it is not only in these exceptional cases that the advantages of leisure will appear. Ordinary men and women, having the opportunity of a happy life, will become more kindly and less persecuting and less inclined to view others with suspicion. The taste for war will die out, partly for this reason, and partly because it will involve long and severe work for all. Good nature is, of all moral qualities, the one that the world needs most, and good nature is the result of ease and security, not of a life of arduous struggle. Modern methods of production have given us the possibility of ease and security for all; we have chosen, instead, to have overwork for some and starvation for others. Hitherto we have continued to be as energetic as we were before there were machines; in this we have been foolish, but there is no reason to go on being foolish forever.
