C0 code coverage information

Generated on Fri Jul 11 15:55:35 -0700 2008 with rcov 0.7.0

Code reported as executed by Ruby looks like this...
and this: this line is also marked as covered.
Lines considered as run by rcov, but not reported by Ruby, look like this,
and this: these lines were inferred by rcov (using simple heuristics).
Finally, here's a line marked as not executed.
