From 865092c656af70bd5317513d8e0ed87fdc1c9acd Mon Sep 17 00:00:00 2001
From: Bruce Hill <bruce@bruce-hill.com>
Date: Mon, 24 Feb 2020 01:31:39 -0800
Subject: Major update: instead of defining all the helper functions as static
 C-strings prefixed to commands (modified by the Makefile), the helper
 functions are now standalone scripts in the helpers/ dir, which gets added to
 "$PATH" when running bb.
