EMERGY SIMULATOR
EmSim simulating a the world natural resources evolution... Diagram (JGraph) driven simulator. Bondgraphs > nonlinear differantial system > plot: implemented for economics and ecology. Network analysis: emergy propagation implemented.

Any suggestions on how to actually use this? The project seems to be defunct, the links to supporting websites are broken, and there's no manual included with the downloaded source files. Any help besides the cryptic description?

Cheers,
