   CoffeeScript is a little language that compiles into JavaScript.
-  
+
   Install Node.js, and then the CoffeeScript compiler:
   sudo bin/cake install
-  
+
+  Or, if you have the Node Package Manager installed:
+  npm install -g coffee-script
+  (Leave off the -g if you don't wish to install globally.)
+
   Compile a script:
   coffee /path/to/script.coffee

+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="pilwrap">                 <a class="pilcrow" href="#section-2">&#182;</a>               </div>               <p>The only dependency is on the <strong>Jison.Parser</strong>.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="p">{</span><span class="nx">Parser</span><span class="p">}</span> <span class="o">=</span> <span class="nx">require</span> <span class="s1">&#39;jison&#39;</span></pre></div>             </td>           </tr>                               <tr id="section-3">             <td class="docs">               <div class="pilwrap">                 <a class="pilcrow" href="#section-3">&#182;</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="pilwrap">                 <a class="pilcrow" href="#section-4">&#182;</a>               </div>               <p>Since we're going to be wrapped in a function by Jison in any case, if our

+<ol>
+<li>Check that all paired tokens are balanced and in order.</li>
+<li>Rewrite the stream with a stack: if you see an <code>EXPRESSION_START</code>, add it
+to the stack. If you see an <code>EXPRESSION_END</code>, pop the stack and replace
+it with the inverse of what we've just popped.</li>
+<li>Keep track of "debt" for tokens that we manufacture, to make sure we end
+up balanced in the end.</li>
