Well - the easiest way is to execute 'import test' after having added
the assembly. This should execute the code in order to create a module.
ScriptScope scope = engine.CreateScope();
ScriptSource source = engine.CreateScriptSourceFromString("import test",
SourceCodeKind.Statements);
engine.Execute(scope);
There is an API for setting a stream as stdout on an engine -
'runtime.IO.SetOutput'.
