Even I searched it a lot when I was new to it and didn't get any info in systematic manner. All I can say is, the information is not available in one place (to the best of my knowledge). I would really appreciate if there is a document with all the options with their meaning mentioned.
So far I only copy my working export file and simply change the path to files. But I always wanted to know all the details about the other parameters compiled in one place.
