It would be great if we could have a documentation system that basically formed a tree of use-cases (perhaps inspired by the python documentation, ACL and PCL to start with) and then contained tutorial style guides on using functionality for different outcomes.
Current thinking: a series of html pages that form a tree of headings, with each linking to a blog entries. People could add recommended modifications through the blog comments, and then I could filter that into a tight set of technical documentation, all in the same style.
Reader - if you're enthusiastic for this let me know ideas for variations - I'm finishing a contract today and could start setting something up like this tomorrow. The timing of this release is good for me.
