Git/color prompt

To show the status of the current project in the bash prompt, using color, add this to ~/.bashrc:

parse_git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h \[\033[01;32m\]\w\[\033[33m\]\$(parse_git_branch)\[\033[00m\] $ "

I think the location is significant; in my files, it's right after PS1 is first defined.
