+Ruby CoffeeScript
+=================
+
+Ruby CoffeeScript is a bridge to the official CoffeeScript compiler.
+
+    CoffeeScript.compile File.read("script.coffee")
+
+
+Installation
+------------
+
+    gem install coffee-script
+
+*Note: This compiler library has replaced the original CoffeeScript
+ compiler that was written in Ruby.*
+
+
+Dependencies
+------------
+
+This library depends on the `coffee-script-source` gem which is
+updated any time a new version of CoffeeScript is released. (The
+`coffee-script-source` gem's version number is synced with each
+official CoffeeScript release.) This way you can build against
+different versions of CoffeeScript by requiring the correct version of
+the `coffee-script-source` gem.
+
+In addition, you can use this library with unreleased versions of
+CoffeeScript by setting the `COFFEESCRIPT_SOURCE_PATH` environment
+variable:
+
+    export COFFEESCRIPT_SOURCE_PATH=/path/to/coffee-script/extras/coffee-script.js
+
+### JSON
+
+The `json` library is also required but is not explicitly stated as a
+gem dependency. If you're on Ruby 1.8 you'll need to install the
+`json` or `json_pure` gem. On Ruby 1.9, `json` is included in the
+standard library.
+
+### ExecJS
+
+The [ExecJS](https://github.com/sstephenson/execjs) library is used to automatically choose the best JavaScript engine for your platform. Check out its [README](https://github.com/sstephenson/execjs/blob/master/README.md) for a complete list of supported engines.

+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
+* [therubyrhino](https://github.com/cowboyd/therubyrhino) - Mozilla
+  Rhino embedded within JRuby
+* [Johnson](https://github.com/jbarnette/johnson) - Mozilla
+  SpiderMonkey embedded within Ruby
+* [Mustang](https://github.com/nu7hatch/mustang) - Mustang V8
+  embedded within Ruby
+* [Node.js](http://nodejs.org/)
+* Apple JavaScriptCore - Included with Mac OS X
+* [Mozilla SpiderMonkey](http://www.mozilla.org/js/spidermonkey/)
+* [Microsoft Windows Script Host](http://msdn.microsoft.com/en-us/library/9bbdkx3k.aspx) (JScript)
+
+A short example:
+
+    require "execjs"
+    ExecJS.eval "'red yellow blue'.split(' ')"
+    # => ["red", "yellow", "blue"]
+
+A longer example, demonstrating how to invoke the CoffeeScript compiler:
+
+    require "execjs"
+    require "open-uri"
+    source = open("http://jashkenas.github.com/coffee-script/extras/coffee-script.js").read
+
+    context = ExecJS.compile(source)
+    context.call("CoffeeScript.compile", "square = (x) -> x * x", :bare => true)
+    # => "var square;\nsquare = function(x) {\n  return x * x;\n};"
+
+# Installation
+
