Hi @yoursanonymous,
Thanks. I am aware of it and I merged that in my branch for testing.
We are also looking into resolving #77 and planning to update that together.
Meanwhile, please also send us you suggestions for details of Windows build so we can get that included in README.md as well.
regards,
Joseph

Thanks for the update.
Glad to hear the changes have been pulled into the branch for testing.

I appreciate you taking a look and integrating this. I will follow up shortly with details and suggestions for the Windows build so they can be included in the README as discussed.

Thanks again
