+# take the package specifier for embark_version and use `npm pack` to retrieve
+# a tarball, unpack, and then process json file in embark that gives the
+# supported locales and the default; use `npx json ...` to process into two
+# files that can be easily read by bash; copy those files into builder-base
+# (remaining steps are in the next builder image) and loop over the list of
+# locales in the 'supported' file using the sed technique to uncomment in
+# /etc/locale.gen, then run `dpkg-reconfigure locales`; in a later step use the
+# info in the 'default' file as argumets for `update-locale` (unless builder
+# args are defined, see below); the reason to prefer doing this w/ a node
+# builder image vs. downloadig jq into builder-base (deleting jq at the end) is
+# that `npm pack` is best suited to handling an EMBARK_VERSION value that could
+# be any valid npm package specifier; once this is in place, probably still
+# want to keep the __LANG (and related) builder args, but get rid of the
+# default values, only do the sed step for them if they're defined; rather than
+# setting ENV LANG, may prefer to do similar in docker-entrypoint based on the
+# value in 'default' file (would need to copy it over), but only if it's not
+# already defined, e.g. by it being forwarded with `docker run -e`, as run.sh
+# does

+# TODO make the nodez theme prettier by changing the color of the = and ver
+# numbers to match the blue color used to report PWD
