"Promoted build"

Does anyone know what this piece of code from the Shooter Game example’s ShooterGameEditor.Target.cs does:


    public override GUBPProjectOptions GUBP_IncludeProjectInPromotedBuild_EditorTypeOnly(UnrealTargetPlatform HostPlatform)
    {
        var Result = new GUBPProjectOptions();
        Result.bIsPromotable = true;
        return Result;
    }

I’ve got a hunch, but I assume it is not something I need in my project.
