Install prezto to a vagrant/*nix box with a single command

prezto-install.sh

#!/bin/zsh
#
# This script installs prezto into a vagrant/*nix box which already has zsh and oh-my-zsh
# installed. It also replaces the prompt color and enables the git prezto module. If
# executed via the suggested command below, also the default shell is changed into zsh.
# BTW, if using this for a vagrant box, be sure to execute the command while ssh'd into
# the box.
#
# Usage: curl -L https://raw-gist-file-address-here.sh | zsh && chsh -s $(which zsh)
