usage_description="
Runs all of the scripts given as arguments against multiple MariaDB versions using docker

Uses mariadb.sh to boot a MariaDB docker environment and pipe source statements in to the container

Sources each script in MariaDB in the order given

Runs against a list of MariaDB versions from the first of the following conditions:

- If \$MARIADB_VERSIONS environment variable is set, then only tests against those versions in the order given
- If \$GET_DOCKER_TAGS is set and dockerhub_show_tags.py is found in the \$PATH (from DevOps Python tools repo), then uses it to fetch the latest live list of version tags available from the dockerhub API, reordering by newest first
- Falls back to the following pre-set list of versions, reordering by newest first:

$(tr ' ' '\n' <<< "$mariadb_versions")
