Did Google publish their public developer documentation tooling/generators? I'm talking about the documentation available from the
https://developers.google.com/ family of URLs. E.g. https://developers.google.com/protocol-buffers/docs/overview or https://developers.google.com/closure/compiler/docs/gettingstarted_app.
All of their developer documentation is obviously consistently styled, and seems to include lots of machine-generated content.
The closest I found to a public variant of this tooling is in the Web Fundamentals sources. Is that it? Or is there a more canonical source for the tooling?
