That's a lot of screen scraping. :)

It would be good to capture this as part of the documentation IMO

I think that would be much better.

I think it would also be helpful to have an option (-I) to
disable index search.  There will be cases where people
don't want to put distributions in PyPI and won't want to have
to implement an index server.  The find-links mechanism seems to
work fine most of the time.
