Hi Vincent,
let me explain a few things about our revision control usage:
We use centralized subversion, so you have to get an account from Stefan before you can commit. I have added Stefan to this message. (Usually, developers can apply for an account after they have submitted a few patches and the patches were accepted. Only very few developers on this list have accounts with commit permissions.) Everything you commit will directly appear in the public tree and you can't change the commit message later. So if you want to send a patch for review, do _not_ commit it, but run svn diff. The output of svn diff can be mailed to the list for review. After you get an Acked-by from someone on the list, you can commit.
Regards, Carl-Daniel
