New option to run multiple engines through the same test:

--engine="myisam,archive"

--number-of-rows has been removed for the time being and replaced with
 option to allow you to just repeat multiple time all of the inserts you specifed with data. When number-of-rows-returns it will be instead used for averaging rows while growing concurrency. 

Returned stats now has accurent row and query counts since it includes a multiple for the rows and queries added.

Parser is now a touch smarter and understands end of file issues if you have a delimiter at the end of the file.
