This tool has been written in 2021 as a one-time proof of concept to import
Oscar station metadata into Wikidata. It's not meant to be used outside of this
controlled environment as it would inevitably lead any careful user to
insert duplicates and wrong information into the Wikimedia project.

The full original code remains available here for educational purpose.

For up to date code, see the repository at
