PS1="\W$(__git_ps1) $ "

I actually don't use the git alias stuff becuase I have more complete git alias in my gitconfig.. Micah what is the PS1 regex stuff all about?

the PS1 variable sets the prompt text and colorizes it. Basically this is what it outputs:

username currentdirectory (gitbranch) $

It's pretty sweet.
