Hi all,
Sorry, I was gone for a long week-end taking advantage on a public
holiday (date?) and I unfortunately missed the irc meeting.
We (Bertil and I) will do our best to get more involved in the future
discussions.
Thanks Bart for the summary.
Looks like it is difficult for all of us to go the same way but I hope we can.
Regards
Pierre
