If you look at the code in the version control system (either svn, or
the git mirror) it should be clearer as none of the generated files
are checked in (whereas the tar files we distribute include the
generated files for convenience).
If you look at one of the languages where the wrapping has been done
in a natural way, you should see the sort of thing to aim for. Python
is probably the best example of this (but ignore the *3.py files which
are mostly generated from the *2.py files by the Python 2to3 tool, with
some manual tweaks to work around issues with that tool).
