* Usage note:
* This module makes a best effort to export the same data we would internally.
* At Facebook we use a server-generated module that does the parsing and
* exports the data for the client to use. We can't rely on a server-side
* implementation in open source so instead we make use of an open source
* library to do the heavy lifting and then make some adjustments as necessary.
* It's likely there will be some differences. Some we can smooth over.
* Others are going to be harder.
