I'm working for the Software Revolution, and we just finished an automated documentation of the LINUX kernel and its various components (memory-management, IPC, security, etc.) Anyways, the documentation consists of hyperlinked scalable graphics for control flow graphs, structure charts, state machines, action diagrams, data element tables, call charts... the list goes on... The documentation is posted at www.softwarerevolution.com/jeneral/open-source-docs.html [1]. It is completely free of course, and we'd like to get some feedback as to what people developing or working with the LINUX kernel think of it. I will try to keep track of responses in this forum, but if you want you may also send feedback to nranewcomb@hotmail.com [2]. Note that you will need a browser with SVG display capablities. I would recommend Firefox, but the Microsoft IE works too. Thanks for your time - Nick
