-This package contains different sources for different users:
-
-1. The files located in the root folder can be consumed using CommonJS
-2. The files under `/es6` are es6 compatible files that can be transpiled to
-   es5 using any transpiler. This contains:
-    * `dev/`: a development version that includes runtime type assertions
-    * `prod/`: a production version that does not include runtime type assertions
-3. The files under `/ts` are the Typescript source files
-
-As a convenience, we provide you with `/es6/{dev|prod}/es5build.js`, a script to transpile the es6 sources into es5
-using [Google Traceur](https://github.com/google/traceur-compiler/).
