Indeed, I only searched the online devel archive, but I forgot to search my mail.
Thanks, indeed I found that link (it is on the github page).
Now let's hope we can get it to (non-GNU) ELPA sooner or later, but from his
answer I guess he is willing to 'hand-over' the package at some point. He just
needs some help with that (and I would be happy to assist). But as he is still
developing, it might be better to wait a little. Therefore, the main reason for my
mail was to notify you about the package (I guess it does not hurt, to get
notified about it twice :)
Thank you all for your replies!
