Among the many code tools out there, this one has always seemed a far reach for me -- interpreting code complexity and putting a metric on how "good" code is.
From Andre Loker (whose blog I discovered only recently), comes a fairly deep review.They offer a time-bombed trial version that's licensed for use for open source products, and promise to release an extended license before the time bomb has hit. I imagine this is to keep a close tab on their license without granting it in perpetuity.
Odd licensing aside, there is a wealth of information in the reports it generates, and in a turn that I found particularly interesting, it's able to import NCover reports. I'm about to give it a try on my FileCombiner application, though it may take quite a bit of reading in order to get any meaningful information about the results it gives.
