Hi, Encouraged by Boost Library Incubator initiative I wanted to make a review of FIT library, but I found I had some questions to Paul - the author. I send my questions also here, in case you are not subscribed for the comments in Boost Library Incubator. Please see my comment here: http://rrsd.com/blincubator.com/bi_library/fit-3/?gform_post_id=1100 Regards, &rzej
