[clue] Unzipping zip archives with duplicates?

[Sean LeBlanc]

As for how they got in there - it's thanks to a certain vendor and how 
they export some data - they produce a zip file with dupes in there. 
Because it's legal I guess? Not necessarily a best practice, I would 
think, to do this just because a zip file supports this.

As far as what you're talking about - I'm not quite sure how I'd do this 
- it's non-deterministic, and to give you an idea of what I'm dealing 
with, there are 114 duplicates in the file, and for any given run, I'm 
sure the names would collide.
