Personally I'd vote `StdGen`, and it follows llvm's `TableGen`.  The name `std-include-mapping/generate.py` seems too verbose...

renamed to `STDGEN_CODE_PREFIX`.

I think either way works.

+// Used to build a lookup table (qualified names => include headers) for C++

The version of HTML archive is the date information, but this information is only present in the `.zip` name, we lose it after we unzip the `zip` file....
