After some learning experience (*cough*) I committed a new version of the scripts, now in $DEV_TOOLS/release that go so far as staging local changes to all repositories after a successful vote.
I will test some more tomorrow and add the announce mailing part. The real test will then come when actually doing a release as testing is hard to cover all code paths otherwise. I have silently sneaked in - as some fringe benefit to all the pain - a '-rcN' suffix for vote candidates. Since we will be able to cancel a release much later now without modifying a source repository. The -rcN tars for voting are named as such, but the directories contained have the version without any suffix. So, a -rcN tar can be renamed to the release tar without changes when the vote has passed. Cheers, Stefan
