Aliases have nothing to do with Objective-C, they're only dealt with
from Carbon.
import os
from Carbon.File import FSResolveAliasFile, FSRef
def resolve_alias(path):
# resolve an alias, if not an alias then it will just return the
# given path.
return FSResolveAliasFile(path, True)[0].as_pathname()
def is_alias(path):
# return 1 if an alias, 0 otherwise
return FSRef(path)[0]
