Here we go, your script could look like the following and you need to 
call your installer that way:

your_installer --script your_script.qs

var installerTargetDirectory="c:\\auto-test-installation";

function Controller()
{
     installer.autoRejectMessageBoxes;
     installer.setMessageBoxAutomaticAnswer( "OverwriteTargetDirectory", 
QMessageBox.Yes);
     //maybe we want something like this
     //installer.execute("D:\\cleanup_directory.bat", new 
Array(installerTargetDirectory));
     installer.setMessageBoxAutomaticAnswer( "stopProcessesForUpdates", 
QMessageBox.Ignore);
}

Controller.prototype.IntroductionPageCallback = function()
{
     gui.clickButton(buttons.NextButton);
}

Controller.prototype.TargetDirectoryPageCallback = function()
{
     var page = gui.pageWidgetByObjectName("TargetDirectoryPage");
page.TargetDirectoryLineEdit.setText(installerTargetDirectory);
     gui.clickButton(buttons.NextButton);
}

Controller.prototype.ComponentSelectionPageCallback = function()
{
}

Controller.prototype.LicenseAgreementPageCallback = function() {}
Controller.prototype.StartMenuDirectoryPageCallback = function() {}
Controller.prototype.ReadyForInstallationPageCallback = function() {}
Controller.prototype.PerformInstallationPageCallback = function(){}
Controller.prototype.FinishedPageCallback = function() {}

In my last response I forgot to tell that there is a global "gui" object 
as well. So to sum it up, depending on your needs you need to use the 
global objects and either connect them, call some functions or just 
access member like the status enums. Basically all Q_PROPERTY, 
Q_INVOKABLE , SIGNALS and SLOTS should be available from inside the scripts.
