I prefer to work with text-based tools and I've spent quite a few hours creating a development environment that I feel comfortable with. These dotfiles are the result.
All color settings (vim themes, for example) have been developed with my Xdefaults/iTerm2 colors in mind, so if you're going to use any of these dotfiles make sure you also download the .Xdefaults file (at least if you want the color theme I originally intended).
Tested on FreeBSD and OSX. Use at your own risk. :-)
