If 'dst' is a directory, then 'src' is copied there with the same name;

    the current platform) is copied.  If 'preserve_times' is true (the
    default), the last-modified and last-access times are copied as well.
    If 'update' is true, 'src' will only be copied if 'dst' does not exist,
    or if 'dst' does exist but is older than 'src'.

'link' allows you to make hard links (os.link) or symbolic links
    (os.symlink) instead of copying: set it to "hard" or "sym"; if it is
    None (the default), files are copied.  Don't set 'link' on systems that
    don't support it: 'copy_file()' doesn't check if hard or symbolic
    linking is available. If hardlink fails, falls back to
    _copy_file_contents().

Under Mac OS, uses the native file copy function in macostools; on
    other systems, uses '_copy_file_contents()' to copy file contents.

Return a tuple (dest_name, copied): 'dest_name' is the actual name of
    the output file, and 'copied' is true if the file was copied (or would
    have been copied, if 'dry_run' true).
