Solve the following python programming problem given the following code:
@ ValidateLarchPlugin 
def restore(fname, group = None, _larch = None) : 
    'restore groups and data from an hdf5 Larch Save file

    restore(fname, group=None)

    Parameters
    ----------
       fname   name of output Larch save file (required)
       group   top-level group to put data in [None]

   Returns
   -------
       top-level grouop containing restored subgroups and data.

   If group is None, a group will be created and returned.
