fs = {
      writeFile : function(file, content, encoding, cb) {
        written[file] = JSON.parse(content);
        cb();
      }
    };

    // Supress all logging during tests

      , verbose :  function () {}
      , silly   :  function () {}
      , error   :  function () {}

    publish = proxyquire.resolve('../lib/publish', __dirname, { 
        fs      :  fs
      , './utl' :  utl
      , npmlog  :  log 
    });
