Remarks

• This is the installation script for these dotfiles and their local counterparts.

• This can be run anywhere and will install the dotfiles in the current directory, but it is really meant to be run in $HOME.

• If you're not me, the user and email settings won't make a lot of sense.

• This is destructive! If you want to preserve your existing dotfiles, back them up first.

• To get the local dotfiles, use the -l option with the desired branch name (see example below).

• Using the raw link to this Gist, initializing on a new machine takes just

  cd "$HOME"
  bash <(curl -L https://git.io/JJczn)
  bash <(curl -L https://git.io/JJczn) -l t460s

  to get the common dotfiles and the local ones for branch t460s.
