How to use the traceur.util function in traceur

inData.push(data || '');
  try {
    var o = JSON.parse(inData.join(''));

    /*
      o.source
      o.options
      o.file
      o.originalFile
    */

    traceur.options = o.options;
    traceur.options.sourceMaps = true;
    traceur.options.modules = 'parse';

    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 traceur = require('traceur');

// this hack is needed because the traceur developers have made the
// command line compiler modules private. without this we won't get
// the automatic dependency resolution done by parsing the modules
// 'import' statements.
