A few notes:
You can get at the tar via the io archive streams in setup.
Shelling out to do this isn't an option.. setup is used in some places
to populate corporate mini-mirrors, without cygwin being installed.=20
Regarding size of changes: I'd rather a series of small patches, each
taking one step to the goal, adding up to lots of changes, than a small
patch that does the job badly.

Cheers,
Rob
