C++ is one of my most experienced languages. It is also one of my most hated languages. Things seem to be that way, the more you interact with something, the more polarized you get.
I have used it for several years now for various projects. The most difficult and largest of which was Satori. I've written a number of class libraries with it that I have used over time.
When I get the python code written, I will post documentation and archives of my C++ code.
