This module provides 2 functions:
ishidden(path):
    returns whether the object at "path" is hidden

sethidden(path, toggle):
    if toggle is True, sets the object at "path" as hidden
    returns the new path to object (it might change under non windows systems)

Both of them might raise an OSError if given path is not found.
This module requires pywin32 under Windows."""
