+from this grammar file. Jison is a bottom-up parser generator, similar in
+style to <a href="http://www.gnu.org/software/bison">Bison</a>, implemented in JavaScript.
+It can recognize <a href="http://en.wikipedia.org/wiki/LR_grammar">LALR(1), LR(0), SLR(1), and LR(1)</a>
+type grammars. To create the Jison parser, we list the pattern to match
+on the left-hand side, and the action to take (usually the creation of syntax
+tree nodes) on the right. As the parser runs, it
+shifts tokens from our token stream, from left to right, and
+<a href="http://en.wikipedia.org/wiki/Bottom-up_parsing">attempts to match</a>
+the token sequence against the rules below. When a match can be made, it
+reduces into the <a href="http://en.wikipedia.org/wiki/Terminal_and_nonterminal_symbols">nonterminal</a>
+(the enclosing name at the top), and we proceed from there.</p>
+
+<p>If you run the <code>cake build:parser</code> command, Jison constructs a parse table
+from our rules and saves it into <code>lib/parser.js</code>.</p>             </td>             <td class="code">               <div class="highlight"><pre></pre></div>             </td>           </tr>                               <tr id="section-2">             <td class="docs">               <div class="octowrap">                 <a class="octothorpe" href="#section-2">#</a>               </div>               <p>The only dependency is on the <strong>Jison.Parser</strong>.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="nv">Parser: </span><span class="nx">require</span><span class="p">(</span><span class="s1">&#39;jison&#39;</span><span class="p">).</span><span class="nx">Parser</span></pre></div>             </td>           </tr>                               <tr id="section-3">             <td class="docs">               <div class="octowrap">                 <a class="octothorpe" href="#section-3">#</a>               </div>               <h2>Jison DSL</h2>             </td>             <td class="code">               <div class="highlight"><pre></pre></div>             </td>           </tr>                               <tr id="section-4">             <td class="docs">               <div class="octowrap">                 <a class="octothorpe" href="#section-4">#</a>               </div>               <p>Since we're going to be wrapped in a function by Jison in any case, if our

+a series of passes over the token stream, using this <strong>Rewriter</strong> to convert
+shorthand into the unambiguous long form, add implicit indentation and
+parentheses, balance incorrect nestings, and generally clean things up.</p>             </td>             <td class="code">               <div class="highlight"><pre></pre></div>             </td>           </tr>                               <tr id="section-2">             <td class="docs">               <div class="octowrap">                 <a class="octothorpe" href="#section-2">#</a>               </div>               <p>Set up exported variables for both Node.js and the browser.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="k">if</span> <span class="nx">process</span><span class="o">?</span>

As you
+generate code, you create a tree of scopes in the same shape as the nested
+function bodies. Each scope knows about the variables declared within it,
+and has a reference to its parent enclosing scope. In this way, we know which
+variables are new and need to be declared with <code>var</code>, and which are shared
+with the outside.</p>             </td>             <td class="code">               <div class="highlight"><pre></pre></div>             </td>           </tr>                               <tr id="section-2">             <td class="docs">               <div class="octowrap">                 <a class="octothorpe" href="#section-2">#</a>               </div>               <p>Set up exported variables for both <strong>Node.js</strong> and the browser.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="k">this</span><span class="p">.</span><span class="nv">exports: </span><span class="k">this</span> <span class="nx">unless</span> <span class="nx">process</span><span class="o">?</span>

+      <b class="header" style="margin-top: 20px;">0.7.0</b>
+      Official CoffeeScript variable style is now camelCase, as in JavaScript.
+      Reserved words are now allowed as object keys, and will be quoted for you.
+      Range comprehensions now generate cleaner code, but you have to specify <tt>by -1</tt>
+      if you'd like to iterate downward. Reporting of syntax errors is greatly 
+      improved from the previous release. Running <tt>coffee</tt> with no arguments
+      now launches the REPL, with Readline support. The <tt>&amp;-</tt> bind operator
+      has been removed from CoffeeScript. The <tt>loop</tt> keyword was added,
+      which is equivalent to a <tt>while true</tt> loop. Comprehensions that contain
+      closures will now close over their variables, like the semantics of a <tt>forEach</tt>.
+      You can now use bound function in class definitions (bound to the instance).
+      For consistency, <tt>a in b</tt> is now an array presence check, and <tt>a of b</tt>
+      is an object-key check. Comments are no longer passed through to the generated
+      JavaScript.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.6.2</b>
+      The <tt>coffee</tt> command will now preserve directory structure when
+      compiling a directory full of scripts. Fixed two omissions that were preventing
+      the CoffeeScript compiler from running live within Internet Explorer.
+      There's now a syntax for block comments, similar in spirit to CoffeeScript's heredocs.
+      ECMA Harmony DRY-style pattern matching is now supported, where the name
+      of the property is the same as the name of the value: <tt>{name, length}: func</tt>.
+      Pattern matching is now allowed within comprehension variables. <tt>unless</tt>
+      is now allowed in block form. <tt>until</tt> loops were added, as the inverse
+      of <tt>while</tt> loops. <tt>switch</tt> statements are now allowed without
+      switch object clauses. Compatible
+      with Node.js <b>v0.1.95</b>.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.6.1</b>
+      Upgraded CoffeeScript for compatibility with the new Node.js <b>v0.1.90</b>
+      series.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.6.0</b>
+      Trailing commas are now allowed, a-la Python. Static
+      properties may be assigned directly within class definitions,
+      using <tt>@property</tt> notation.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.5.6</b>
+      Interpolation can now be used within regular expressions and heredocs, as well as
+      strings. Added the <tt>&lt;-</tt> bind operator.
+      Allowing assignment to half-expressions instead of special <tt>||=</tt>-style
+      operators. The arguments object is no longer automatically converted into
+      an array. After requiring <tt>coffee-script</tt>, Node.js can now directly
+      load <tt>.coffee</tt> files, thanks to <b>registerExtension</b>. Multiple
+      splats can now be used in function calls, arrays, and pattern matching.
+    </p>
+
+    <p>
+      <b class="header" style="margin-top: 20px;">0.5.5</b>
+      String interpolation, contributed by
+      <a href="http://github.com/StanAngeloff">Stan Angeloff</a>.
+      Since <tt>--run</tt> has been the default since <b>0.5.3</b>, updating
+      <tt>--stdio</tt> and <tt>--eval</tt> to run by default, pass <tt>--compile</tt>
+      as well if you'd like to print the result.
+    </p>
+
     <p>
       <b class="header" style="margin-top: 20px;">0.5.4</b>
       Bugfix that corrects the Node.js global constants <tt>__filename</tt> and
       <tt>__dirname</tt>. Tweaks for more flexible parsing of nested function
       literals and improperly-indented comments. Updates for the latest Node.js API.
