+# This .inc file allows you to build and deploy multiple sets of kernel + modules with different defconfigs
+#
+# Note that this include will NOT stage anything nor create packages, since that is virtuall impossible
+# Userspace should be built against the 'regular' kernel
+#
+# The intended usecase is for machines that has mutually exclusive drivers due to e.g. pinmuxing issues.
+# For example the LogicPD omap-l138 experimenter board can have multiple mutually exclusive expansion boards
+# like lcd, ethernet, sound, 20x2 character LCD, etc. To be able to easily test all of those you can use this .inc
+#
+# To make it easier finding the original defconfig from a running kernel, this also forcefully turns on 
+# CONFIG_IKCONFIG_PROC so people can do 'zcat /proc/config.gz' on the target.
