Heavily inspired by Armin Ronacher :)
You will need Armin's vcprompt for the bash prompt: https://bitbucket.org/mitsuhiko/vcprompt
git clone git://github.com/dcramer/dotfiles.git && cd dotfiles && make
The bin/ directory is symlinked into ~/.bin by make install-user.
One of the more useful maintenance scripts is disk-cleanup:
disk-cleanup disk-cleanup --run disk-cleanup --deep
GitHub and commit-signing setup notes live in docs/github.md.
