[guilhem-sante]

Overview

In the purpose of completing of fully argument mining capable CLI client. The client should features a subcommand for the retrievement of the arguments (meaning extracting their argumentational value solely).

The client would be then expected to output the retrieved arguments as a JSON file.
The retrievemnt will be made by sending http requests to a separate service running a Large Language Model.
