I know we're supposed to be focused on the end-result, but I'm really just in awe of the code. Everything is so incredibly well documented, tested, and structured. I already see a few things I want to borrow... will definitely be coming back to this project for ideas.
I second this. I recently made a simple command line tool for my coworkers using several of the same libraries used here, but this is so much cleaner and better organized than what I threw together. Definitely will be reviewing this codebase for inspiration when I get a chance to refactor.
