-# DO NOT EDIT THIS FILE!

-# 	- config.mk is auto-generated from config.mk.in by configure.
-#	  If you edit config.mk your changes will be spammed.
-#
-#	- Settings in this file may be overridden by giving replacement
-#	  definitions in build.mk.  See build.mk.sample for a good
-#	  starting point for a build.mk file.
-#
-#	  If you don't have a build.mk file then you get defaults for everything.
