# Script to reverse engineer the build of a given Debian / Ubuntu server
# I do this all the time: take an existing server, create a Bash / Ansible / Puppet / Chef
# built script, to allow Continuous Depoyment.
# It's tedious, but this script will give you the basics to get started.
# Make sure you have "sudo" access to get all the details.
# setup folders

Convert values between RGB hex codes and xterm-256 color codes.
#! /usr/bin/env python
""" Convert values between RGB hex codes and xterm-256 color codes.
Nice long listing of all 256 colors and their codes. Useful for
developing console color themes, or even script output schemes.
