This is a stand-alone copy of the Phorward C/C++ library that was generated on $TODAY from the [official phorward repository](https://github.com/phorward/libphorward).

It is not intended to be used for further development, but for simple and fast integration into existing projects. To contribute changes, please check out the official repository at https://github.com/phorward/libphorward.

Thank you & have fun!
