+# jval-wrapper.sh - print JSON values to stdout
+#
+# We form a wrapper for the `jval(1)`, a tool that allow the printing of JSON values.
+#
+# We propose that the grammar used by JSONPath.sh(1):
+#
+#   https://github.com/lcn2/JSONPath.sh
+#
+# becomes the model for how `jval(1)` prints JSON values.  Consider, for, example:
+#
+#   JSONPath.sh -w -f 1984/mullender/.entry.json '$author_set..author_handle'
+#
+# and in particular:
+#
+#   JSONPath.sh -w -b -f 1984/mullender/.entry.json '$author_set..author_handle'
+#
+# as a model of printing the `author_handle` values from the JSON `author_set` array.
+#
+# See the following URL for more information.

+# 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.
