Well, folx, I done went and did it. I put the FENIX source code online. Did you ever want to see it for yourself? Maybe thoroughly scrutinize my code and make fun of how bad it was? WELL NOW YOU CAN!

And, if you act now, in a bonus 2-for-1 deal, you can also help! (Isn't that fun?)
Anyhoo, I've put most of what I've got online. Let me know if you have any issues with it.
(And I should mention that that repository isn't all of it. As I say in the readme, I haven't figure out subrepos yet, so bear with me.)
