The ls override gives you colors. The dir override is because I'm a lazy Windows user who types dir by default. autofeature is running autospec, but with features enabled (for Cucumber, mostly). The PS1 export gives you a blue-colored prompt. I know I'm probably weird in this respect, but I run my terminal colors as foreground 64,64,64 on background 222,221,224, which ends up looking like this:
(I also run the terminal window slightly transparent, so you can see a bit of the background behind the window.)
