You can transform Web.config on build. Add this target to *.csproj file:

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\WebApplications\Microsoft.WebApplication.targets" />
<Target Name="BeforeBuild">
    <TransformXml 
        Source="Web.Base.config" 
        Transform="Web.$(Configuration).config" 
        Destination="Web.config" />
</Target>

Keep the origin configuration in Web.Base.config. It's enough to enable transformation and it works for any XML config file. SlowCheetah is no longer needed at all.

XML transformations will only be applied when you publish web apps and not during build.
