# The purpose of this script is to automatically test .C files
# for unnecessary includes by attempting to compile the source
# with specific headers removed.  The expected behavior
# is for the compilation to fail, so if it succeeds that may
# mean you can remove a header from the .C to speed up compilation
# times.  Be sure to double-check or at least know what you are
# doing before just automatically removing header files.
