This is first pass of a script to install Ruby via rbenv, Vim (optional Janus plugs), and zsh (oh-my-zsh).

debian-ruby-install.sh

#! /bin/bash
#
# This simple script will get you a pretty decent Ruby development setup
# for Debian based machines.
#
# Included are: Vim, tmux, Git, zsh, Janus*, rbenv.
#
# Use at your own risk!.. Buhaha
