http://qa.perl.org/phalanx/kwalitee.html says:
What is kwalitee? Kwalitee is inexact quality. We don't know exactly what it is, but we know it when we see it.Isn't that backwards? I thought 'kwalitee' was supposed to be a metric that was exact, and that (hopefully) had some correlation with 'quality'. The whole point is that 'kwalitee' is objectively measurable, while 'quality' isn't.
