You can set installer properties in merge modules by using this format.
I just typically create a subfeature to create a variation point in the installer. You can then put a feature condition on it to control whether the components brought in by the merge modules get installed or not. This is a lot simpler then putting a condition on each component and gives you more flexibility of whether you want to show the "debug symbols" feature to the end user or not.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
