It would be interesting to know how these compare with the failure rates
for other filter programs on the same set of documents.
Without anything to compare these to, it's hard to know if they're good
or bad. For example, perhaps all those 345 failed .doc files are
"readme.doc" and actually plain text. Or perhaps they are all valid and
would be read fine by a different filter.
