ChaiScript is one of the first (and perhaps only) embedded scripting language designed from the ground up to directly target C++. Being a native C++ application, it has some advantages over existing embedded scripting languages: it uses a header-only approach, which makes it easy to integrate with existing projects; it maintains type safety between your C++ application and user scripts; and it supports a variety of C++ techniques including callbacks, overloaded functions, class methods, and STL containers.
