There are various issues with the documents within. Registry: Aside from scanpci being added in 2007, this has not been maintained since originally added in 2003. Driver options and extra drivers have not been added recently, and most of the driver options inside are guesses. exa-driver.txt This references a function that hasn't existed for a while. Since nobody has complained about the function missing, nobody must be referring to it. README.DRIcomp To my knowledge, enabling DRI nowadays is as easy as --enable-dri and building xserver as simple as using jhbuild. This document references things such as building Linux 2.4 and getting a CVS checkout of XFree86, so it's definitely not maintained. v2: Update <a href="http://configure.ac">configure.ac</a> to not generate the doc/devel Makefile.
