Change build script dynamicly

[StyX]

I need to create a setup that changes dynamicly on build time by passing in Compiler Variables.

Simply put I need to change everything that shows version and product name when building the setup. The same install script is used for both testing of new releases and the current release, so in order to avoid having to maintain several build scripts I'd like to merge them all together and just change it based on the variables that is inputted.

The variables I need to change are:

In Project Properties:
Product Name = $TITLE$
Product Version = $VERSION$

In Summary and UAC:
Title = ??
Subject = ??

Services:
Service Name = ??
Display Name = ??
Service Description = ??

Also is it possible to set the name of the shortcut dynamicly?
I saw that it says no variables allowed in the Link Name property. Is there a way around this ?
