Great work, Sebastien! Technically, the ICLA or software grant should be submitted directly to the secretary by the contributor, but I would just go ahead and send it along. There is no need to provide any explanation.
Pls forward Michael's note below to priv...@commons.apache.org, so we have an admin record of it. I don't think we need to ask for a grant or formal assignment of copyright for the code being ported, given Michael's note below. Does anyone else? Have fun with the port!
