Making a XNA Game Installer

; Script generated by the Inno Setup Script Wizard.
; (Then extensively modified by Caliban Darklock.)
; (And yet again modified by David Amador) Should work property with XNA 3.1
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!

; The code section doesn't like comments for some reason.
; VerifyDotNet35 removes the .NET setup if you already have .NET 3.5 installed.
; VerifyDotNet35sp1 removes the VC redist if you already have .NET 3.5 SP1, -or-
; if you don't have .NET 3.0 at all (it will be installed along with .NET 3.5).
; Using the skipifdoesntexist flag allows the setup to ignore the missing files.
