Unable to understand how Git's difftool configs are set?

You can see a complete setup using mergetool and difftool here .

You have also (in addition to remembering about many places Git searches for configuration, as stated in response by VonC) to remember that both git-difftool and git-mergetool provide some autodetection / autodiscovery (in some fixed order of preference) of which tools you have available.

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.
