For building the compiled library and API documentation, we use a custom build script written in node.js. It uses the following libraries:

Google Closure requires that Java is installed on the system.

YUI Doc requires that Python is installed on your system, along with the following modules:

  • setuptools
  • Pygments
  • SimpleJSON
  • Cheetah

View the YUI Doc page for more information.

YUI Doc and Google Closure are included in the repository, which makes it easier to run the build, and ensures that we don’t have version mismatches between the source and the libraries.


In order to run the script, you must have node.js installed, along with the wrench and optimist modules.

The easiest way to install the required modules is to first install NPM (node package manager) and then run:

npm install wrench
npm install optimist
