 Nana is a C++ standard-like GUI library designed to allow developers to easily create cross-platform GUI applications with modern C++ style. Currently it is regularly tested on Linux(X11) and Windows, and experimentally on macOS and FreeBSD. The [nana repository](https://github.com/cnjinhao/nana) contains the entire source of the library. You can browse the source code and submit your pull request for contributing.
