Programming Erlang (2nd edition): wrong type mentioned - 'atoms' but should be 'lists' (page 164)

Is this a typo, or did I misunderstand the sentence?

The excerpt from the book:
“The file must contain a function main(Args). When called from an operating system shell, Args will contain a list of the command-line arguments represented as atoms.”

I think it should read:
“The file must contain a function main(Args). When called from an operating system shell, Args will contain a list of the command-line arguments represented as lists.”

Please let me know if I misunderstood.
Thank you
