2.5.2 Alias Objects

`data`
  The raw data for the Alias record, suitable for storing in a resource or transmitting to other programs.

`Resolve` ([file])
  Resolve the alias. If the alias was created as a relative alias you should pass the file relative to which it is. Return the FSSpec for the file pointed to and a flag indicating whether the Alias object itself was modified during the search process. If the file does not exist but the path leading up to it does exist a valid fsspec is returned.

`GetInfo` (num)
  An interface to the C routine `GetAliasInfo()`.

`Update` (file[, file2])
  Update the alias to point to the file given. If file2 is present a relative alias will be created.

Note that it is currently not possible to directly manipulate a resource as an Alias object. Hence, after calling `Update()` or after `Resolve()` indicates that the alias has changed the Python program is responsible for getting the `data` value from the Alias object and modifying the resource.
