Blake Stowell: C++ is one of the properties that SCO owns
today and we frequently are approached by customers who wish
to license C++ from us and we do charge for that. Those
arrangements are done on a case-by-case basis with each
customer and are not disclosed publicly. C++ licensing is
currently part of SCO's SCOsource licensing program.
