The Physical Quantities System review has ended, and, unfortunately, we are going to have to turn it down at this time. However, it is clear from the reviews that there is an enormous amount of interest in the library. I'm really hoping that that Andy Little will continue his work on it and resubmit it for review. Andy has been following the large discussion of PQS, so I will not enumerate the more minor criticisms included there. Some of the major criticisms that influenced my difficult decision include the following: * Many of the reviews liked the documentation, but improvements there would help out for a large number of reviewers. * If the library were more flexible about the type system used, several reviewers would have been happier. However, I would suggest that as long as a plan is in place for improving the flexibility, this should not prevent an initial version of the library from being accepted. * Since the library includes a large number of compile-time type manipulations, it would be great if the library included standard metafunctions to query these types. In addition, following other template metaprogramming conventions established within Boost such as documenting the concepts used would be a great help. I'd like to thank Andy Little for the work done so far on PQS and also for responding rapidly to the prolific discussion on the developer's list. -Fred Bertsch
