This was the difficult part. It's not that the information is not provided. It's that I found the information difficult to find. My first attempt was the man pages. But there are none for analog.
Man pages are great in that they always provide the basic command line arguments.
And it was this information which I wanted. I was lost. I should have known. That's a pretty standard place to put documents, as you can tell the from the name. In fact I went there and found only html files.
