Copy file src to dst. The files can be specified as
pathnames or FSSpec objects. If createpath is non-zero
dst must be a pathname and the folders leading to the
destination are created if necessary. The method copies data and
resource fork and some finder information (creator, type, flags) and
optionally the creation, modification and backup times (default is to
copy them). Custom icons, comments and icon position are not copied.
Tell the finder that some bits of finder-information such as creator
or type for file dst has changed. The file can be specified by
pathname or fsspec. This call should tell the finder to redraw the
files icon.
Note that the process of creating finder aliases is not specified in
the Apple documentation. Hence, aliases created with mkalias()
could conceivably have incompatible behaviour in some cases.
