That is a good point, however not everyone can build the documentation. I tried a while back and the whole documentation subsystem is /soo/ fragile its untrue. You have to have the exact right versions installed and hope that the exact right versions have configured themselves to work together correctly, otherwise you get cryptic unsolvable error messages. Tex is notorious for these problems. When I tried to generate the docbook stuff, after spending a significant amount of time trying to debug it, I just gave up completely with any ideas about ever adding to the documentation. I've since decided that I am /never/ going to do anything past adding docbook comments to files. If someone cares about linking them into the rest of the docbook system, and they have the capability to generate the docbook output, then that's fine and dandy, but I believe that requiring everyone to have that capability is asking far too much. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
