[boost] NPC International is using boost

With about 800 restaurants, NPC International is the world's largest Pizza Hut franchisee. Our company's web site is: www.npcinternational.com. We make extensive use of boost in our internally developed point of sale, restaurant management, communications, and accounting systems. We use the following libraries in approximate order of frequency of use: bind function optional shared_ptr date_time thread lambda type_traits mpl tuple enable_if variant spirit string_algo preprocessor filesystem operator iterators tokenizer Many, many thanks, Brock Peabody
