## How to contribute to CoffeeScript
* Before you open a ticket or send a pull request, [search](https://github.com/jashkenas/coffeescript/issues) for previous discussions about the same feature or issue. Add to the earlier ticket if you find one.
* Before sending a pull request for a feature, be sure to have [tests](https://github.com/jashkenas/coffeescript/tree/master/test).
* Use the same coding style as the rest of the [codebase](https://github.com/jashkenas/coffeescript/tree/master/src). If you're just getting started with CoffeeScript, there's a nice [style guide](https://github.com/polarmobile/coffeescript-style-guide).
* In your pull request, do not add documentation to `index.html` or re-build the minified `coffee-script.js` file. We'll do those things before cutting a new release.

CoffeeScript is a little language that compiles into JavaScript. Think
of it as JavaScript's less ostentatious kid brother -- 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>A simple <strong>OptionParser</strong> class to parse option flags from the command-line.
Use it like so:</p>
<pre><code>parser = <span class="hljs-keyword">new</span> OptionParser switches, helpBanner
options = parser.parse process.argv
</code></pre><p>The first non-option is considered to be the start of the file (and file
option) list, and all subsequent arguments are left unparsed.</p>
</div>

</li>
<li id="section-3">
<div class="annotation">
<div class="pilwrap ">
<a class="pilcrow" href="#section-3">&#182;</a>
</div>
<p>Initialize with a list of valid options, in the form:</p>
<pre><code>[short-flag, long-flag, description]
</code></pre><p>Along with an optional banner for the usage help.</p>
</div>
<div class="content"><div class='highlight'><pre> constructor: <span class="hljs-function"><span class="hljs-params">(rules, @banner)</span> -&gt;</span>
@rules = buildRules rules</pre></div></div>
</li>
<li id="section-4">
<div class="annotation">
<div class="pilwrap ">
<a class="pilcrow" href="#section-4">&#182;</a>
</div>
<p>Parse the list of arguments, populating an <code>options</code> object with all of the
specified options, and return it. Options after the first non-option
argument are treated as arguments. <code>options.arguments</code> will be an array
containing the remaining arguments. This is a simpler API than many option
parsers that allow you to attach callback actions for every flag. Instead,
youre responsible for interpreting the options object.</p>
