    -r, --run                        compile and run a script (requires Narwhal)
    -o, --output [DIR]               set the directory for compiled JavaScript
    -w, --watch                      watch scripts for changes, and recompile
    -p, --print                      print the compiled JavaScript to stdout
    -l, --lint                       pipe the compiled JavaScript through JSLint
    -e, --eval                       compile a cli scriptlet or read from stdin
    -t, --tokens                     print the tokens that the lexer produces
    -v, --verbose                    print at every step of code generation
    -n, --no-wrap                    raw output, no safety wrapper or vars
        --install-bundle             install the CoffeeScript TextMate bundle
        --version                    display CoffeeScript version

-      <a href="http://github.com/jashkenas/coffee-script/blob/master/src/grammar.coffee">small DSL</a>
-      on top of the <a href="http://github.com/zaach/jison">Jison parser generator</a>, and is available
-      as a <a href="http://nodejs.org/">Node.js</a> utility. The core compiler however,
-      does not depend on Node, and can be run in other server-side-JavaScript environments,
-      or in the browser (see "Try CoffeeScript", above). This may be helpful,
-      as Node only run on flavors of nix, and not Windows, for the time being.

+      Here's a wish list of things that would be wonderful to have in
+      CoffeeScript:
+    </p>
 
     <ul>
       <li>
-        <a href="http://github.com/jashkenas/coffee-script/">Source Code</a><br />
-        Use <tt>bin/coffee</tt> to test your changes,<br />
-        <tt>bin/cake test</tt> to run the test suite,<br />
-        <tt>bin/cake build</tt> to rebuild the CoffeeScript compiler, and <br />
-        <tt>bin/cake build:parser</tt> to regenerate the Jison parser if you're
-        working on the grammar.
+        A JavaScript version of the compiler, perhaps using Alessandro Warth's
+        <a href="http://tinlizzie.org/ometa/">OMeta</a>.
       </li>
       <li>
-        <a href="http://github.com/jashkenas/coffee-script/issues">CoffeeScript Issues</a><br />
-        Bugs reports, feature requests, and general discussion all belong here.
+        Ideas for alternate syntax to end blocks of expressions &mdash; the periods
+        can look a little weird with deeply nested structure. (There's now a
+        'whitespace' branch &mdash; help add significant whitespace over there.)
       </li>
       <li>
-        If you'd like to chat, stop by <tt>#coffeescript</tt> on Freenode.
+        Test cases for any syntax errors you encounter that you think CoffeeScript
+        should be able to compile properly.
+      </li>
+      <li>
+        A tutorial that introduces CoffeeScript from the ground up for folks
+        without knowledge of JavaScript.
+      </li>
+      <li>
+        Integration with Processing.js's JavaScript API (this would depend on
+        having a JavaScript version of the compiler).
+      </li>
+      <li>
+        A lot of the code generation in <tt>nodes.rb</tt> gets into messy
+        string manipulation. Techniques for cleaning this up across the board
+        would be appreciated.
       </li>
     </ul>

-    <p>
-      <b class="header" style="margin-top: 20px;">0.5.1</b>
-      Improvements to null soaking with the existential operator, including
-      soaks on indexed properties. Added conditions to <tt>while</tt> loops,
-      so you can use them as filters with <tt>when</tt>, in the same manner as
-      comprehensions.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.5.0</b>
-      CoffeeScript 0.5.0 is a major release, While there are no language changes,
-      the Ruby compiler has been removed in favor of a self-hosting
-      compiler written in pure CoffeeScript.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.3.2</b>
-      <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>
-      Arguments objects are now converted into real arrays when referenced.
-    </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.
+      from outside of the CoffeeScript directory. Bugfix for nested

     <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
+      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>.

-This folder includes rough cuts of CoffeeScript syntax highlighters for 
-TextMate and Vim. Improvements to their lexing ability are always welcome.
-
-To install the TextMate bundle, drop it into:
-  ~/Library/Application Support/TextMate/Bundles
-
-To install the Vim highlighter, copy "coffee.vim" into the "syntax" directory of
-your vim72, and enable it in either of the following two ways:
-
-  * Manually, by running `:set syntax=coffee`
-  
-  * Or automatically, by creating a "filetype.vim" file within "~/.vim", which
-    contains something along these lines:

-    end
