At best TUSC is a crutch;
- it seems not to be aware of SUL
- it introduces a new user with a new password
- it clutters your talk page with some necessary gibberish
- the upload is done by a bot anyway
This software already exists for MediaWiki for years.
The upload functionality however does work. Now for an invitation to do more localisations; maybe the template can provide information to find more untranslated SVG graphics.
