Usage: createrfifile.pl rss_cpp_deps_file.d output_file.rfi [exclude path]

Takes a file containing CPP dependency output from the preprocessing of a .rss file and
generates a "combined resource" .rfi that can  be consumed by CDB.
Optionally takes an exclusion path under which "found" dependencies are then ignored.
