This package is a very thin wrapper on top of https://github.com/JuliaOpt/AmplNLWriter.jl that automatically downloads an appropriate Couenne solver binary from https://ampl.com/products/solvers/open-source/ . CouenneNL.jl provides the CouenneNLSolver
type, which is a wrapper around the AmplNLSolver
from AmplNLWriter.jl.
