To build the latest patchlevel of X11 for Slackware 11.0, use the files in this directory to add or replace the ones that shipped with the distribution in source/x/x11/. Build the packages with ./x11.SlackBuild, and then use upgradepkg to upgrade the rebuilt packages. The x11, x11-devel, x11-xdmx, x11-xnest, and x11-xvfb server packages are the ones that should be upgraded.
