Yes, you can set an environment variable in one build step and use it in the following step. You will need to use a service message in your build script as described here http://confluence.jetbrains.net/display/TCD65/Build+Script+Interaction+with+TeamCity#BuildScriptInteractionwithTeamCity-AddingorChangingaBuildParameterfromaBuildStep to dynamically update a build parameter, which you can use in the next step. Note, that it won't be available in the step that generates it, only in the next one.
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.
