Although nobody asked, I thought it might be relevant to show how to do this with simples3:

>>> b.copy("my_bucket/file.txt", "file_copy.txt", acl="public")

I'm not sure what Boto does here, but it's worth noting that the permissions (ACL) will not be copied by S3, it will be reset to "private" if nothing else is specified. To copy the ACL, you have to ask for it first.
