(** The [full_context] allows the client {!command} handlers to work in
     various modes (command line, batch mode, web client, etc.) by
     abstracting some basic operations such as logging and reading
     configuration options. It is passed as parameter to the command
     handler when running a command, and must be transmitted to all
     basic operations, also making client commands reantrant. *)
