I don't understand what this is. There are a pile of .cpp files. The Perl interface - I presume there is one - isn't documented at all.
The readme states: "probably to be released under GNU-GPL at some point, or something, once it's not quite such an embarrassing piece of code". Perhaps the author should consider taking it away from the CPAN and thus save us the annoyance of having to see something this useless (in its current state) in the first place, and also think twice before uploading in future.
