I started adding info from the old packaging guide to the wiki this afternoon.. I'm trying to update it with current best practices / processes as I go, as well as adding additional tips / tricks / links where they fit in.
If any one is interested in proofreading / critiquing, take a look here:http://www.pclinuxos.com/wiki/index.php/Category:Packaging
..and post your feedback / suggestions back in this thread.
PS.. If anyone is interested in translating, feel free to jump in! I have set up links at the top of the page for other languages. The easiest way is probably to just use the edit button on a page to copy the existing content and layout, hit the back button, click on the language you would like to translate it to, and when you get to the edit box for the new translation paste in the original content and translate it.
