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