## LOCALMODCONFIG OPTION
 # As of mainline 2.6.32, running with this option will only build the modules that you currently have
 # probed in your system VASTLY reducing the number of modules build.
 #
 # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
 # Read, https://bbs.archlinux.org/viewtopic.php?pid=830221#p830221
 # To keep track of which modules are needed for your specific system/hardware, give graysky's module_db script
 # a try: http://aur.archlinux.org/packages.php?ID=41689
 #
 # Note that if you use graysky's script, this PKGBUILD will auto run the reload_data base for you to probe
 # all the modules you have logged!
