This article is now published on my website: Prefer Subshells for Context.

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

	#!/usr/bin/env sh

	# To test the script, set the GNUPGHOME to a temporary directory, e.g:
	# $ export GNUPGHOME="$(mktemp -d)"

	set -eu -o pipefail

	DEPENDENCIES="gpg git"
	EXPIRATION="${EXPIRATION:-6m}"
	ALGORITHM="${ALGORITHM:-RSA}"
