There's a further issue, as relates to .dist-info. If a wheel were to
incorporate dependencies, then installing a wheel would lead to different
results from e.g. installing from source, unless the wheel contained a
.dist-info for all the distributions in the wheel. The spec makes no mention of
multiple .dist-info files - were these ever intended to be there? I had assumed
not. If multiple dists in a wheel are to be entertained, it would make more
sense to *always* have .data/purelib and .data/platlib (I know they are
generally always the same, but whatever :-).

Sorry I never brought this up earlier - I just assumed that wheels were for
one distribution, only in a binary format. They're still a win if that's the
case, it's just that playing with the wheeler.py script got me thinking about
dependencies...
