; This script shows how to insert custom wizard pages into Setup and how to handle
; navigation between those pages if multiple custom pages are inserted after each
; other. Furthermore it shows how to 'communicate' between the [Code] section and
; the regular Inno Setup sections using {code:...} constants and finally it shows
; how to customize the settings text on the 'Ready To Install' page.
