Script pour installation facile Erlang 19.2 + Elixir 1.4.0

#!/bin/bash

# This script installs Erlang 19.2 from source and Elixir 1.4.0
# from precomplized zip. Installation took approximately
# 40 minutes with a crappy computer and crappy internet connection.
# This script should work (read: was only tested) on Mint
# Rebecca 17.3, but honestly should work on most Linux debian distros.
# Linut Mint 18, but honestly should work on most Linux debian distros.

# INSTRUCTIONS:
# Pull this into a directory that will persist. (not tmp)
# $ chmod u+x install_erlang_and_elixir.sh
# $ sudo ./install_erlang_and_elixir.sh
# Logout and Log in.

# For additional help visit Elixir's IRC channel @ #elixir-lang
# on freenode (everyone is very helpful)

# Made by Jason Goldberger
# Updated by Jeremy Montesinos

# This script comes with no guarantees with regards to
# security or safety. Use at your own risk.
