Cxxomfort (cxx as in C++, comfort as in comfort) is a small, header-only library that backports some of the nifty goodies and features from the more recent C++ Standards to previous Standards such as C++03 or C++11. I wrote it originally to facilitate my working with the evolving C++ standard as I was getting back into the language. It is intended to reduce the amount and stress of code rewrite while at the same time assisting in backwards and forwards portability.
You can include only cxxomfort/base.hpp in library code if you only need the base subset of cxxomfort features, without TR1-related utilities or any other sort of advanced features. Features for more information.
