(** Usage [format_program fmt p type_dependencies_ordering]. Either one of these
    may be set:

    - [exec_scope] will mark the named scope as "main" and execute it at the end

    - [exec_args] will add support for executing scopes passed on Argv (default
      true if [exec_scope] is [None] *)
