+# check-requirements.sh checks all requirements files for each top-level
+# convert*.py script.
+#
+# WARNING: This is quite IO intensive, because a fresh venv is set up for every
+# python script. As of 2023-12-22, this writes ~2.7GB of data. An adequately
+# sized tmpfs /tmp or ramdisk is recommended if running this frequently.
+#
+# usage: check-requirements.sh [<working_dir>]
+# check-requirements.sh nocleanup [<working_dir>]
+#
+# where:
+# - <working_dir> is a directory that can be used as the base for
+# setting up the venvs. Defaults to `/tmp`.
+# - 'nocleanup' as the first argument will disable automatic cleanup
+# of the files created by this script.
+#
+# requires:
+# - bash >= 3.2.57
+# - shellcheck
+#
+# For each script, it creates a fresh venv, `pip install`s the requirements, and
+# finally imports the python script to check for `ImportError`.
