It is not abandoned, I am the maintainer. The documentation covers the APIs of the package but not the “zen” of the wider OTP framework, for that the official OTP documentation and existing books are recommended.
That’s great information, thanks. I seem to recall checking the commit history and it didn’t seem dead, but I’m also accustomed to experimental packages being dropped early and often. Do you want help with maintenance or are you doing this independently?
I'm not at that level yet, but I'd love to if I get there. I look at projects like these and wonder what the hell I've been doing with my career. Thanks for the invite!
