How to use the fortune.RSVP function in fortune

var fortune = require('fortune')
  , orm = require('orm')
  , RSVP = fortune.RSVP
  , _ = fortune._;

var adapter = {};

adapter._init = function(options) {
  var _this = this;

  // Setup ORM instance.
  this.orm = orm.connect({
    host: options.host,
    database: options.db,
    protocol: options.adapter,
    user: options.username,
    password: options.password,
    port: options.port,
    query: options.flags

    fortune.RSVP.rethrow(e);
    console.error("error authenticating user: ", e);
    res.send(500);
  });
}

  endedAt: Date,
  requestedBy: 'family',
  performedBy: {ref: 'family', inverse: 'sittings'}
}).

resource("token", {
  owner: 'family',
  value: String
