# The top level Makefile invokes this Bourne shell script after ensuring
# that the build.conf file is present.  The job of this script is to grok
# that configuration file and to produce include/config.{h,mk,m4} files
# corresponding to the selected configuration.
#
# The current directory is expected to be the top level of nuc-fw, i.e.,
# all fragments are sourced as cfgmagic/blah.
# Don't run this script directly - let the Makefile do it for you.
