Someone else commented on the VP that we have no
documentation on DjVu
which I found to be true, from how to create DJvu files, to how to use
them in MediaWiki. I had a look on
mediawiki.org and couldn't find
anything too useful either. So any hints here would be appreciated.
We already have that in French on French Wikisource.
It just needs to be copied to Commons and translated.
And there is a {{djvu}} template.
