We welcome efforts to remove our existing python-2.7 scripts to
-replace them either with Bash or, at your choice, python-3.6+.
+replace them either with portable shell scripts or,
+at your choice, python-3.6+.
If you contribute new python based testcases, we advise you to
not repeat our past misfortunes and write the tests in a standard
test framework like for example pytest.
+
+For writing portable shell scripts, these tools are useful:
+@uref{https://github.com/koalaman/shellcheck, Shellcheck},
+@uref{https://salsa.debian.org/debian/devscripts/blob/master/scripts/checkbashisms.pl, checkbashisms},
+@uref{http://www.etalabs.net/sh_tricks.html},
+@uref{https://wiki.ubuntu.com/DashAsBinSh},
+and @uref{https://mywiki.wooledge.org/Bashism}
+
+@c You could also run "bin/check_shell_script" (which we still have
+@c to write).
