+ExecJS
+======
+
+ExecJS lets you run JavaScript code from Ruby. It automatically picks
+the best runtime available to evaluate your JavaScript program, then
+returns the result to you as a Ruby object.
+
+ExecJS supports these runtimes:
+
+* [therubyracer](https://github.com/cowboyd/therubyracer) - Google V8
+  embedded within Ruby for exceptional performance
+* [Node.js](http://nodejs.org/)
+* [Google V8](http://code.google.com/p/v8/)
+* Apple JavaScriptCore
+* [Mozilla Spidermonkey](http://www.mozilla.org/js/spidermonkey/)
+* [Mozilla Rhino](http://www.mozilla.org/rhino/)
+* [Microsoft Windows Script Host](http://msdn.microsoft.com/en-us/library/9bbdkx3k.aspx) (JScript)
+
+A short example:
+
+    require "execjs"
+    ExecJS.exec "'red yellow blue'.split('')"
+    # => ["red", "yellow", "blue"]
