Hi,

> I added this to the Tutorial.

Thanks.
I backported into Japanese Tutorial.rd.ja.
I also made little changes to the Tutorial.rd. Please refer to
cvs commit log. (I'm sorry not updated Wiki yet.)

I think this may be very good for algorithmic or mathematical methods.
I fear this might not be so good for database parsers, especially
for complex structured data, because they depend on original
data's structure and I think we can hardly describe every location in
original data in every method's unittest where the method's
return value is based on.
