+      a document that also happens to be executable CoffeeScript code. The compiler

+      as code, and ignore the rest as comments.

+
+    <p>
+      Besides being used as an ordinary programming language, CoffeeScript may
+      also be written in "literate" mode. If you name your file with a
+      <tt>.litcoffee</tt> extension, you can write it as a Markdown document &mdash;
+      a document that also happens to be executable CoffeeScript code. The compiler
+      will treat any indented blocks (Markdown's way of indicating source code)
+      as code, and ignore the rest as comments.
+    </p>
+
+    <p>
+      Just for kicks, a little bit of the compiler is currently implemented in this fashion:
+      See it
+      <a href="https://gist.github.com/jashkenas/3fc3c1a8b1009c00d9df">as a document</a>,
+      <a href="https://raw.github.com/jashkenas/coffee-script/master/src/scope.litcoffee">raw</a>,
+      and <a href="http://cl.ly/LxEu">properly highlighted in a text editor</a>.
+    </p>
+
+    <p>
+      I'm fairly excited about this direction for the language, and am looking
+      forward to writing (and more importantly, reading) more programs in this style.

+    </h2>
+
+    <p>
+      CoffeeScript 1.6.1 and above include support for generating source maps,
+      a way to tell your JavaScript engine what part of your CoffeeScript
+      program matches up with the code being evaluated. Browsers that support it
+      can automatically use source maps to show your original source code
+      in the debugger. To generate source maps alongside your JavaScript files,
+      pass the <tt>--map</tt> or <tt>-m</tt> flag to the compiler.
+    </p>
+
+    <p>
+      For a full introduction to source maps, how they work, and how to hook
