Hi Crunch Maintainers, In Secion 2.5 Common Do Fn Patterns<http://crunch.apache.org/user-guide.html#mapfn> the last sentence in the third paragraph (the one about mapFn) isn't proper English.
"...it's easy to test a MapFn by verifying that a given input returns a every input record will have exactly one output, it's easy to test a MapFn by verifying that a given input returns a given output.." the two phrases also seem redundant. J
