    the file exists, it will be ruthlessly clobbered.)  If 'preserve_mode'
    is true (the default), the file's mode (type and permission bits, or
    whatever is analogous on the current platform) is copied.  If
    'preserve_times' is true (the default), the last-modified and

    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.

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).
