OLE decoders are nearly as prolific as IRC clients and GNOME mail clients.
Your current options are:
COLE
laola
wv's modified laola
libole2 (in gnumeric)
and now the KOffice OLE decoder, too.
I mean no offense to anyone working on such a decoder, I just find it
amusing that there are so many while it seems like such an unappealing
coding project (poor [and occassionally incorrect] documentation, arcane
file formats, lots of testing/reverse-engineering).
