Extented version of OSR

Dear Prof. Juillard,

I am trying to draw an efficiency frontier for my open economy model. Karam, Laxton et al (2008) draws this frontier by using an extended version of the Optimal Simple Rule (OSR) routine in DYNARE. I was wondering if this version is publicly available.
In one of the forums, you say documentation has not ready for this routine yet. I was wondering if it is available now. Any information that you can give will definitely help me. Thanks so much.

I appreciate your help.
