exceptions.TypeError: <lambda>() takes exactly 2 arguments (1 given)

I fiddled around with the code and figured out how to make it work.

Two things...
1. I made the matches lambda a function, mainly because I'm not good with lambda and I didn't see what the difference was from the spec vs the code in storage.py.
2. I added archives as an argument to createMetaFile() in writer.py because after the fix in #1, that was complaining.

I've attached a patch, it should apply cleanly.

Side question: Is there plans to support python < 2.6 ?

This got fixed in the 0.9.5 release
