Amazon Linux 2015.09 for LetsEncrypt beta installer

amazon_linux_letsencrypt_installer.sh

#!/bin/bash

#
# Amazon Linux (2015.09.1 x86_64 minimal HVM EBS: ami-fbb9c991)
#
# See: https://gist.github.com/kennwhite/aa74c164bcdf092a7a10 for more background & notes
# The use case is a standalone build on stock distro, then ssh push cert/keys to 
#  public-facing web server (nginx, etc). IMHO, there are too many dev packages
#  required for Internet-exposed production boxes, but your use case may vary.

# If you get stuck, just:
#   cd ~/ && rm -rf ./letsencrypt && rm -rf ~/.local/share/letsencrypt
# and try again.
# 

# Usage (as root; note the leading space): . amazon_linux_letsencrypt_installer.sh

# A little insane, so read and run at your own risk!!!

# This installs pyenv manager to run non-system multiple/parallel versions of python
# (Rationale in short: LE official python client requires very specific versions of libraries)
