* Final LGPL switch step by adjusting the file headers * Remaining issues (just slightly related to the unittest switch): * No working unittest solution for msvc2005 yet * Unittests not working with mingw + scons either though this seems hard to impossible to fix without an expert in this field * sample_unit_test.cpp would need to get modified for unittest++; it still contains the old boost unittest code
