BTW seems #46 is a simpler solution with better coverage

halturin commented 3 years ago

I've already added bsd-family support in the otp2324 branch.

https://github.com/halturin/ergo/blob/otp2324/bsd.go

you may adjust this PR to these changes so I can merge it.

halturin commented 2 years ago

just released 2.0.0 with the BSD family support
