+This is an attempt to make Facebook's react library more usable from
+CoffeeScript without escaping into JSX or painfully contorting syntax. Here's
+what I have so far.
+
+```coffee
+class Welcome extends Component
+  render: ->
+    @div ->
+      @text "Hello"
+      @span @props.name
+
+component = new Welcome(name: "World")
+element = component.buildElement()
+```
