+# firewall - run only with a bash that is version 5.1.8 or later
+#
+# The "/usr/bin/env bash" command must result in using a bash that
+# is version 5.1.8 or later.
+#
+# We could relax this version and insist on version 4.2 or later. Versions
+# of bash between 4.2 and 5.1.7 might work. However, to be safe, we will require
+# bash version 5.1.8 or later.
+#
+# WHY 5.1.8 and not 4.2? This safely is done because macOS Homebrew bash we
+# often use is "version 5.2.26(1)-release" or later, and the RHEL Linux bash we
+# use often use is "version 5.1.8(1)-release" or later. These versions are what
+# we initially tested. We recommend you either upgrade bash or install a newer
+# version of bash and adjust your $PATH so that "/usr/bin/env bash" finds a bash
+# that is version 5.1.8 or later.
+#
+# NOTE: The macOS shipped, as of 2024 March 15, a version of bash is something like
+# bash "version 3.2.57(1)-release". That macOS shipped version of bash
+# will NOT work. For users of macOS we recommend you install Homebrew,
+# (see https://brew.sh), and then run "brew install bash" which will
+# typically install it into /opt/homebrew/bin/bash, and then arrange your $PATH
+# so that "/usr/bin/env bash" finds "/opt/homebrew/bin" (or whatever the
+# Homebrew bash is).
+#
+# NOTE: And while MacPorts might work, we noticed a number of subtle differences
+# with some of their ported tools to suggest you might be better off
+# with installing Homebrew (see https://brew.sh). No disrespect is intended
+# to the MacPorts team as they do a commendable job. Nevertheless we ran
+# into enough differences with MacPorts environments to suggest you
+# might find a better experience with this tool under Homebrew instead.
