*nix dotfile heaven with git + post-merge hook

I've horsed around with managing my dotfiles using svn and git but never took a really systematic approach before. Now I've seen the light! I introduce to you git-dotfiles.

Well, I've been to one world fair, a picnic, and a rodeo, and that's the stupidest thing I ever heard come over a set of earphones. You sure you got today's codes?
