Publish script?

There isn't any script. Of course, if someone creates it, all the better. (IMHO it should be MediaWiki's devs' responsibility but it seems they think it's ours.)

This does the trick:

grep -h '@author' * | sed 's/ \* @author //' |  sort -b |uniq |sed 's/^.*/* [[User:&|&]]/'

2271 authors at the moment. If there are entries that are similar, they should most likely be fixed by hand.

Output available now: Translating:MediaWiki/Credits/script

P.s. I wonder how Echo notifications in LiquidThread threads on talk pages do (not) trigger a notification...

Echo? Where?

Yes, that's what I did. Fixed by hand where? I just reviewed the list manually before posting it here, I don't think there's anything to fix in the files.
