The output can then be used by other systems, for instance to book the corresponding travel or to visualize it on a map and calendar and to share it with others. travelccm makes an extensive use of existing open-source libraries for increased functionality, speed and accuracy. In particular the Boost (C++ Standard Extensions Install the travelccm package if you need a library of basic C++ objects for Customer-Choice Modeling (CCM), mainly for simulation purpose.
