file copy shutil

[Joe]

I see this on python.org

"Caveat: On MacOS, the resource fork and other metadata are not used.
For file copies, this means that resources will be lost and file type
and creator codes will not be correct."

Is there a way to copy files correctly on BOTH Mac and Windows?  I am
trying to write a utility that will work on both platforms identically
since I am in a mixed environment network.  Thanks.
