#!/usr/bin/env bash
# Purpose: plain text tar format
# Limitations: - only suitable for text files, directories, and symlinks
# - stores only filename, content, and mode
# - not designed for untrusted input
# Note: must work with bash version 3.2 (macOS)
set -o errexit -o nounset
# Sanitize environment (for instance, standard sorting of glob matches)
