--- Comment #21 from Sveinar Søpler cybermax@dexter.no --- This have to be submitted by the patch-writer, unless you perhaps get on IRC or something and talk to one of the devs to help you with this.
Those that have done it 100000000 times think the patch-mailing-list thingy wine uses is ez-pz, but for other mere mortals it is a daunting task i must admit.
Good luck :)
