There is a help information in the code for the argument "-w" saying that "Comma separted list of week numbers to download e.g., 1,3,8". So I supposed that it must be the one that defines which week of courses you want to download. But when I used it, I found it didn't work as I supposed. It indeed indicates the lesson number, or the "index" which is used as the definition in the source code.
So I suggest that the help information be modified as lesson number or sequence number or anything like that. The original hint, "week numbers", is too ambiguous.
Finally, thank you for your works.
