Hey, thanks for working on this!

I have been meaning to rewrite calcpkg for a while (the index searching code is terrible, for instance), so I've put off trying to port it to Python 3. But it is probably worth porting the current implementation anyway!

I'm not so keen on the PEP8 formatting changes, but I don't really mind, and it's a minor price to pay for a working python 3 implementation.

I will look through this and make sure nothing is horribly broken, and then merge into master.

Awesome thanks :)

What PEP8 rules do you not like? I have to use PEP8 at work, and thus my editor is setup to automatically enforce them. I could mess around with disabling specific rules for just this projects if you'd prefer.

The main one is the 80 characters per line limitation-- I think that 120 is probably more reasonable these days. I also don't really believe text should be wrapped if it goes a "little" over (for example, a string that is a few extra characters long) just to meet an arbitrary limit.

I don't really mind when it's done, I just don't stick to it myself.

I'm also of the opinion that line limits based on old printers are silly. It looks like I can setup per-project configuration (http://damnwidget.github.io/anaconda/anaconda_settings/), so I'll update my line length limit.
