+  CoffeeScript is a little language that compiles into JavaScript.
+  
+  Install the compiler:
+  gem install coffee-script
+  
+  Compile a script:
+  coffee /path/to/script.coffee
+  
+  For documentation, usage, and examples, see:
+  http://jashkenas.github.com/coffee-script/
+  
+  To suggest a feature or report a bug:
+  http://github.com/jashkenas/coffee-script/issues/
+
+  The source repository:
+  git://github.com/jashkenas/coffee-script.git
+  
+  To build CoffeeScript from source, install the "racc" gem and
+  run "rake build:parser". Then bin/coffee will work.

+    <h1><sub style="font-size: 100px;">&#9749;</sub> CoffeeScript</h1>
+
+    <p>
+      CoffeeScript is a little language that compiles into JavaScript. Think
+      of it as JavaScript's less ostentatious kid brother &mdash; the same genes,
+      roughly the same height, but a different sense of style. Apart from a handful of
+      bonus goodies, statements in CoffeeScript correspond one-to-one with their
+      equivalent in JavaScript, it's just another way of saying it.
+    </p>
+
+    <p>
+      <b>Disclaimer:</b>
+      CoffeeScript is just for fun and seriously alpha. I'm sure that there are still
+      plenty of holes in the walls and leaks in the roof. <i>There are no guarantees
+      that the syntax won't change between versions.</i> That said,
+      it compiles into clean JavaScript (the good parts) that can use existing
+      JavaScript libraries seamlessly, and passes through
+      <a href="http://www.jslint.com/">JSLint</a> without warnings. The compiled
+      output is quite readable &mdash; pretty-printed, with comments
+      preserved intact.

+      For a longer CoffeeScript example, check out
+      <a href="documentation/underscore.html">Underscore.coffee</a>, a port
+      of the <a href="http://documentcloud.github.com/underscore/">Underscore.js</a>
+      library of helper functions. Underscore.coffee can pass the entire Underscore.js
+      test suite. The CoffeeScript version is faster than the original for a number
+      of methods (in general, due to the speed of CoffeeScript's array comprehensions), and
+      after being minified and gzipped, is only 241 bytes larger than the original
+      JavaScript version.
+      Additional examples are included in the source repository, inside the
+      <a href="http://github.com/jashkenas/coffee-script/tree/master/examples/">examples</a> folder.
+    </p>
+
+    <h2 id="installation">Installation and Usage</h2>
+
+    <p>
+      The CoffeeScript compiler is written in pure Ruby, and is available
+      as a Ruby Gem.
+    </p>
+
+    <pre>
+gem install coffee-script</pre>
+
+    <p>
+      Installing the gem provides the <tt>coffee</tt> command, which can
+      be used to compile CoffeeScript <tt>.coffee</tt> files into JavaScript, as
+      well as debug them. In conjunction with
+      <a href="http://nodejs.org/">Node.js</a> (or <a href="http://narwhaljs.org/">Narwhal</a>), the <tt>coffee</tt>
+      command also provides direct evaluation and an interactive REPL.
+      When compiling to JavaScript, <tt>coffee</tt> writes the output
+      as <tt>.js</tt> files in the same directory by default, but output
+      can be customized with the following options:
+    </p>
+
+    <table>
+      <tr>
+        <td width="25%"><code>-i, --interactive</code></td>
+        <td>

+      <i>
+        This reference is structured so that it can be read from top to bottom,
+        if you like. Later sections use ideas and syntax previously introduced.
+        Familiarity with JavaScript is assumed.
+        In all of the following examples, the source CoffeeScript is provided on
+        the left, and the direct compilation into JavaScript is on the right.
+      </i>
+    </p>
+
+    <p id="whitespace">
+      <b class="header">Significant Whitespace</b>
+      CoffeeScript uses Python-style significant whitespace: You don't need to
+      use semicolons <tt>;</tt> to terminate expressions, ending
+      the line will do just as well. Semicolons can still be used to fit
+      multiple expressions onto a single line. Instead of using curly braces
+      <tt>{ }</tt> to delimit blocks of code (like <a href="#functions">functions</a>,
+      <a href="#conditionals">if-statements</a>,
+      <a href="#switch">switch</a>, and <a href="#try">try/catch</a>),
+      use indentation.
+    </p>
+
+    <p>
+      You don't need to use parentheses to invoke a function, if you're passing
+      arguments:<br /><tt>print "coffee"</tt>
+    </p>
+
+    <p>
+      You can use newlines to break up your expression into smaller pieces,
+      as long as CoffeeScript can determine that the line hasn't finished yet.
+    </p>
+
+    <p id="functions">
+      <b class="header">Functions and Invocation</b>
+      Functions are defined by a list of parameters, an arrow, and the
+      function body. The empty function looks like this: <tt>-></tt>. All
+      functions in CoffeeScript are named by default, for easier debugging.
+    </p>
+    <%= code_for('functions', 'cube(5)') %>
+    <p>
+      If you'd like to create an anonymous function, just wrap it in parentheses:
+      <tt>((x) -> x * x)</tt>
+    </p>
+
+    <p id="assignment">
+      <b class="header">Assignment</b>
+      Use a colon <tt>:</tt> to assign, as in
+      <a href="http://json.org">JSON</a>. Equal signs are only needed for
+      mathy things.
+    </p>
+    <%= code_for('assignment', 'greeting') %>
+    <p>
+      Declaration of new variables are pushed up to the top of the nearest
+      lexical scope, so that assignment may always be performed within expressions.
+    </p>
+
+    <p id="objects_and_arrays">
+      <b class="header">Objects and Arrays</b>
+      Object and Array literals look very similar to their JavaScript cousins.
+      When you spread out each assignment on a separate line, the commas are
+      optional. In this way, assigning object properties looks the same as
+      assigning local variables, and can be moved around freely. Feel free to mix
+      and match the two styles.
+    </p>
+    <%= code_for('objects_and_arrays', 'song.join(",")') %>
+
+    <p id="lexical_scope">
+      <b class="header">Lexical Scoping and Variable Safety</b>
+      The CoffeeScript compiler takes care to make sure that all of your variables
+      are properly declared within lexical scope &mdash; you never need to write
+      <tt>var</tt> yourself.
+    </p>
+    <%= code_for('scope', 'new_num') %>
+    <p>
+      Notice how the all of the variable declarations have been pushed up to
+      the top of the closest scope, the first time they appear.
+      <b>num</b> is not redeclared within the inner function, because it's
+      already in scope; the <b>new_num</b> within the function, on the other hand,
+      should not be able to change the value of the external variable of the same name, and
+      therefore has a declaration of its own.
+    </p>
+    <p>
+      Although suppressed within this documentation for clarity, all
+      CoffeeScript output is wrapped in an anonymous function:
+      <tt>(function(){ ... })();</tt> This safety wrapper, combined with the
+      automatic generation of the <tt>var</tt> keyword, make it exceedingly difficult
+      to pollute the global namespace by accident.
+    </p>
+    <p>
+      If you'd like to create top-level variables for other scripts to use,
+      attach them as properties on <b>window</b>, or on the <b>exports</b>

+      optional guard clauses and the value of the current array index.
+      Unlike for loops, array comprehensions are expressions, and can be returned

+      If you know the start and end of your loop, or would like to step through

+      You might have noticed how even though we don't add return statements
+      to CoffeeScript functions, they nonetheless return their final value.
+      The CoffeeScript compiler tries to make sure that all statements in the

+    </p>
+    <p>

+      JavaScript's prototypal inheritance has always been a bit of a

+      <a href="http://prototypejs.org/">Prototype.js</a>,
+      <a href="http://jsclass.jcoglan.com/">JS.Class</a>, etc.
+      The libraries provide syntactic sugar, but the built-in inheritance would
+      be completely usable if it weren't for a couple of small exceptions:
+      it's awkward to call <b>super</b> (the prototype object's
+      implementation of the current function), and it's awkward to correctly
+      set the prototype chain.
+    </p>
+    <p>
+      CoffeeScript provides <tt>extends</tt>
+      to help with prototype setup, <tt>::</tt> for quick access to an

+      syntax. When you assign an array or object literal to a value, CoffeeScript

+      <tt>@property</tt> is now a shorthand for <tt>this.property</tt>.<br />
+      Switched the default JavaScript engine from Narwhal to Node.js. Pass
+      the <tt>--narwhal</tt> flag if you'd like to continue using it.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.3.0</b>
+      CoffeeScript 0.3 includes major syntax changes:
+      <br />
+      The function symbol was changed to
+      <tt>-></tt>, and the bound function symbol is now <tt>=></tt>.
+      <br />
+      Parameter lists in function definitions must now be wrapped in parentheses.
+      <br />
+      Added property soaking, with the <tt>?.</tt> operator.
+      <br />
+      Made parentheses optional, when invoking functions with arguments.
+      <br />
+      Removed the obsolete block literal syntax.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.2.6</b>
+      Added Python-style chained comparisons, the conditional existence
+      operator <tt>?=</tt>, and some examples from <i>Beautiful Code</i>.
+      Bugfixes relating to statement-to-expression conversion, arguments-to-array
+      conversion, and the TextMate syntax highlighter.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.2.5</b>
+      The conditions in switch statements can now take multiple values at once &mdash;
+      If any of them are true, the case will run. Added the long arrow <tt>==></tt>,
+      which defines and immediately binds a function to <tt>this</tt>. While loops can
+      now be used as expressions, in the same way that comprehensions can. Splats
+      can be used within pattern matches to soak up the rest of an array.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.2.4</b>
+      Added ECMAScript Harmony style destructuring assignment, for dealing with
+      extracting values from nested arrays and objects. Added indentation-sensitive
+      heredocs for nicely formatted strings or chunks of code.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.2.3</b>
+      Axed the unsatisfactory <tt>ino</tt> keyword, replacing it with <tt>of</tt> for
+      object comprehensions. They now look like: <tt>for prop, value of object</tt>.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.2.2</b>
+      When performing a comprehension over an object, use <tt>ino</tt>, instead
+      of <tt>in</tt>, which helps us generate smaller, more efficient code at
+      compile time.
+      <br />
+      Added <tt>::</tt> as a shorthand for saying <tt>.prototype.</tt>
+      <br />
+      The "splat" symbol has been changed from a prefix asterisk <tt>*</tt>, to
+      a postfix ellipsis <tt>...</tt>
+      <br />
+      Added JavaScript's <tt>in</tt> operator,
+      empty <tt>return</tt> statements, and empty <tt>while</tt> loops.
+      <br />
+      Constructor functions that start with capital letters now include a
+      safety check to make sure that the new instance of the object is returned.
+      <br />
+      The <tt>extends</tt> keyword now functions identically to <tt>goog.inherits</tt>
+      in Google's Closure Library.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.2.1</b>

+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.2.0</b>
+      Major release. Significant whitespace. Better statement-to-expression
+      conversion. Splats. Splice literals. Object comprehensions. Blocks.
+      The existential operator. Many thanks to all the folks who posted issues,
+      with special thanks to
+      <a href="http://github.com/kamatsu">Liam O'Connor-Davis</a> for whitespace
+      and expression help.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.1.6</b>
+      Bugfix for running <tt>coffee --interactive</tt> and <tt>--run</tt>
+      from outside of the CoffeeScript directory. Bugfix for nested
+      function/if-statements.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.1.5</b>
+      Array slice literals and array comprehensions can now both take Ruby-style
+      ranges to specify the start and end. JavaScript variable declaration is
+      now pushed up to the top of the scope, making all assignment statements into
+      expressions. You can use <tt>\</tt> to escape newlines.
+      The <tt>coffee-script</tt> command is now called <tt>coffee</tt>.

+      <b class="header" style="margin-top: 20px;">0.1.4</b>
+      The official CoffeeScript extension is now <tt>.coffee</tt> instead of
+      <tt>.cs</tt>, which properly belongs to
+      <a href="http://en.wikipedia.org/wiki/C_Sharp_(programming_language)">C#</a>.
+      Due to popular demand, you can now also use <tt>=</tt> to assign. Unlike
+      JavaScript, <tt>=</tt> can also be used within object literals, interchangeably
+      with <tt>:</tt>. Made a grammatical fix for chained function calls
+      like <tt>func(1)(2)(3)(4)</tt>. Inheritance and super no longer use
+      <tt>__proto__</tt>, so they should be IE-compatible now.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.1.3</b>
+      The <tt>coffee</tt> command now includes <tt>--interactive</tt>,
+      which launches an interactive CoffeeScript session, and <tt>--run</tt>,
+      which directly compiles and executes a script. Both options depend on a
+      working installation of Narwhal.
+      The <tt>aint</tt> keyword has been replaced by <tt>isnt</tt>, which goes
+      together a little smoother with <tt>is</tt>.
+      Quoted strings are now allowed as identifiers within object literals: eg.
+      <tt>{"5+5": 10}</tt>.
+      All assignment operators now use a colon: <tt>+:</tt>, <tt>-:</tt>,
+      <tt>*:</tt>, etc.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.1.2</b>
+      Fixed a bug with calling <tt>super()</tt> through more than one level of
+      inheritance, with the re-addition of the <tt>extends</tt> keyword.
+      Added experimental <a href="http://narwhaljs.org/">Narwhal</a>
+      support (as a Tusk package), contributed by
+      <a href="http://tlrobinson.net/">Tom Robinson</a>, including
+      <b>bin/cs</b> as a CoffeeScript REPL and interpreter.
+      New <tt>--no-wrap</tt> option to suppress the safety function
+      wrapper.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.1.1</b>
+      Added <tt>instanceof</tt> and <tt>typeof</tt> as operators.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.1.0</b>
+      Initial CoffeeScript release.
