Feature Request

Hi all,

Been creating a couple scripts to spin up development environments automatically using poetry in the terminal.

Noticed that there is no --authors flag for poetry init and poetry init --author doesn't seem to accept lists no matter how I seem to input it, figured it'd be a pretty quick implementation to allow some sort of delimiter to input more than one author at a time or add any existing solutions to this issue into the docs.

All the best, Frankie
