Setting Up Clojure on OS X

I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.

I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.

This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.

I appreciate the effort you've put into documenting this, but there are a number of inaccuracies here that need to be addressed. We get

Bearded's Hourly Contract

Date: [[Date of Document]] Between [Our Company] and [Your Company]

Summary

We’re not big on formality, but sometimes it’s best to have a few simple things written down so that we’re all on the same page. In this contract you won’t find complicated legal terms or large passages of unreadable text. We have no desire to trick you into signing something that you might later regret. We do want what’s best for the safety of both parties, now and in the future.
