# 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`.
