Wow, your feedback is really great
Thank you guys.
I'll post the document here and also send it to Gandalf.
The recommended viewer for this is GVIM (preferably with UTL script). With UTL the document feels like a wiki since it contains internal links.
Its quite easy to change to any other format like latex (for generating PDF) or HTML via some script. I can do both if there's demand (though my past experience suggests conversion to latex is much more complex).
