dealbreaker:

>>> age(datetime.date(1970,5,2))
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "c:\python24\lib\site-packages\mx\DateTime\DateTime.py", line
842, in RelativeDateTimeDiff
    diff = date1 - date2
TypeError: unsupported operand type(s) for -: 'DateTime' and
'datetime.date'

I'm getting data from a database, and conversions are out of the
question for something like this. Otherwise it's a fine library :-)
