|
|
* 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.
