The SAGE model is designed to run from the package's top level directory. The
model file (model/sage.gms) is called in a series of single scenarios, whether
that is to specify the baseline or a policy case. See Section 6 in the model's
documentation for an overview of how to run the model and the examples/
subdirectory for a suite of simulation examples.
