Thank you Paul,
It means a lot to me to hear that.
As regards to the status of the project, thank you for the clarification. Also thank
you for undertaking the project! I hope that both of you will continue to improve upon
the code-base and publish those improvements. I know I have learned a lot from
studying the code, I expect others have and will too.
