How to use the traceur.outputgeneration function in traceur

var reporter = new traceur.util.ErrorReporter();
    reporter.reportMessageInternal = function(location, kind, format, args) {
      process.stdout.write(JSON.stringify({ err: kind + '\n' + o.file + location }));
      process.exit(0);
    }

    var parser = new traceur.syntax.Parser(reporter, new traceur.syntax.SourceFile(o.file, o.source));
    var tree = parser.parseModule();

    var project = new traceur.semantics.symbols.Project(o.file);
    var transformer = new traceur.codegeneration.ProgramTransformer(reporter, project);
    tree = transformer.transform(tree);

    // generate source
    var sourceMapGenerator = new traceur.outputgeneration.SourceMapGenerator({ file: o.originalFile });
    var opt = { sourceMapGenerator: sourceMapGenerator };

    var source = traceur.outputgeneration.TreeWriter.write(tree, opt);

    process.stdout.write(JSON.stringify({
      source: source,
      sourceMap: opt.sourceMap
    }));
  }
  catch(e) {
    process.stdout.write(JSON.stringify({ err: e.toString() }));
    return process.exit(0);
  }
});
process.stdin.resume();

process.stdout.write(JSON.stringify({ err: kind + '\n' + o.file + location }));
      process.exit(0);
    }

    var parser = new traceur.syntax.Parser(reporter, new traceur.syntax.SourceFile(o.file, o.source));
    var tree = parser.parseModule();

    var transformer = new traceur.codegeneration.ProgramTransformer(reporter, project);
    tree = transformer.transform(tree);

    var sourceMapGenerator = new traceur.outputgeneration.SourceMapGenerator({ file: o.originalFile });
