    AnCH Framework

    Another C++ Hack

    This project has been migrated to GitHub : https://github.com/vlachenal/anch-framework AnCH framework aims to provide utility classes for some common programming features. Features are implemented to be used as simply as possible. This framework was initially a way to test new C++ specifications (C++11) and to test C++ design patterns and tricks. Only POSIX systems are supported for now. Others could be supported later. (Partial) Doxygen documentation can be found on project home page.
