[Zope-dev] "procedures" for moving package to github and porting to Python 3

Hi, Disclaimer: it's been a while since I actively followed zope-dev and grok-dev. So, please forgive me my ignorance. Spurred by the recent ZTK-2.0 discussion, I'm trying to get back on track on the topics of 1) migrating package to github and 2) porting packages to Python 3. As a first step, I'd like to get the packages directly related to Grok moved over to github. Could someone perhaps tell me if there's a guideline document, some kind of recipe, or perhaps a "conclusive" posting on the mailinglist on how to proceed on this topic? Thanks in advance for any pointers!! kind regards, jw
