This script is intended for use with the cross-build infrastructure self-test during autobuild. The script takes two or more "default.cache.py" files which are the result of the waf configure process, and performs an intelligent comparison - allowing for a limited set of variables to be different. If the configurations are identical (apart from allowed differences) then the script exit with 0 code. If there are differences, the script outputs them to standard output in unified diff format.
