Lets you interface with Steam without running an actual Steam client

var EMsg = Steam.EMsg;
var schema = Steam.Internal;

    if (header.msg in handlers)
      handlers[header.msg].call(this, body, callback);
  }.bind(this));
}

require('util').inherits(SteamUser, EventEmitter);


// Methods

  this._client.send({
    msg: EMsg.ClientLogon,
