This sounds like a good idea. Are you going to update the files in a future CL?
Do you have an example of what it looks like?

Only when you use --release=M21, so not standard Chrome headers.

I mentioned this in IM, but I'll mention it here for posterity...

I think you're going to need to generate all versions of the interfaces in the C
headers, since the C++ layer relies on those now.

Also, I'm fine with this version information appearing in the headers in Chrome
(not just the SDK). I think it's a good idea.
