This C file can be used to build a utility for comparing two NuttX
configuration files.
initialconfig.c
---------------
This is a C file that can be used create an initial configuration.
This permits creating a new configuration from scratch, without
relying on any existing board configuration in place. This utility
will create a barebones .config file sufficient only for
instantiating the symbolic links necesary to do a real configuration.
