[Couenne] Is there a callable library to use Couenne in C/C++?

[Ted Ralphs]

I just wanted to second Tony's suggestion to look at the Optimization
Services project. They have a full-featured API that enables the building
of models in C++ and the ability to pass the model directly to Couenne (or
a number of other solvers) in memory. Writing an nl file is also an option,
but not necessary.

Cheers,

Ted
