# Scan the tree passed as argv[0] for .rsrc files, skipping .rsrc.df.rsrc
# files, and open these. The effect of this is to create the .rsrc.df.rsrc
# cache files if needed.
# These are needed on OSX: the .rsrc files are in reality AppleSingle-encoded
# files. We decode the resources into a datafork-based resource file.
