Perkun (http://sourceforge.net/projects/perkun/) 0.0.9 has been released! It contains multiple classes mentioned previously that facilitate applying heuristics. It contains also a new class - dump_controller, inherited by the optimizer_with_all_data, which controls dumping the data in the verbose mode. It is possible to redirect various data to the XML or text files, to stdout, stderr or a single file. Take a look at the constructor dump_controller::dump_controller in the file dump_controller.cc.
