    Makes the necesary files to convert from plain html of
    Python 1.5 and 1.5.x Documentation to
    Microsoft HTML Help format version 1.1
    Doesn't change the html's docs.

    modified by Dale Nagata for Python 1.5.2

    Renamed from make_chm.py to prechm.py, and checked into the Python
    project, 19-Apr-2002 by Tim Peters.  Assorted modifications by Tim
    and Fred Drake.  Obtained from Robin Dunn's .chm packaging of the
    Python 2.2 docs, at <http://alldunn.com/python/>.
