"""
Small utility to convert MSIE favourites to an object structure.

Originally written by Fredrik Lundh.
Modified by Lars Marius Garshol
2-17-2002 tbp Now closes folder when its traverse is done.  Also works
    with current IE shortcut format, which can differ from the format
    that was assumed here.
