As long as the same thing is done inside a zipped wheel, duplication
of the data is ok by me.  (IOW, if it's a *build-time* step, not an
install step.)  Technically, though, it probably makes the most sense
to do it when the machine-readable metadata is generated, in order to
support in-place builds ala "setup.py develop" and "setup.py test".
