Hi all, after Wave was accepted into Boost I've fixed all of the things mentioned during the review and reported afterwards by different people (thanks a lot for all the comments and help I've got!). Here are the main points: - I've fixed all the problems reported during the review and tried to incorporate all of the remarks done there as well. - The first version of a test suite was implemented and is integrated into the Boost regression process. This test suite currently consists out of more than 100 different unit tests from 2 categories: . Systematic testing of all aspects of the preprocessor as described in the Standard . Set of regression tests collected during the development of Wave over th elast couple of years. The test system is very flexible and is easy to extend. In the future I'll add even more unit tests to check even more details. Since it was asked here before: the test suite currently takes a couple of seconds to execute. The integration of Wave into the regression test procedure revealed some portability issues which I'm currently trying to resolve. - A new sample lexed_tokens was added. It shows how to use one of the C++ lexers included with the library only (without using the C++ preprocessing component). For the details see the Changlog file here: http://tinyurl.com/4fu8m. Overall, I think Boost.Wave is ready for prime time now and can be included into the next Boost release. Regards Hartmut
