(** Tezos Protocol Implementation - Protocol Signature Instance

    This module is the entrypoint to the protocol for shells and other
    embedders. This signature is an instance of
    {{!Tezos_protocol_environment_sigs.V7.T.Updater.PROTOCOL} the
    [Updater.PROTOCOL] signature} from the
    {{:https://tezos.gitlab.io/shell/the_big_picture.html#the-economic-protocol-environment-and-compiler}
    Protocol Environment}.

    Each Protocol depends on a version of the Protocol Environment. For the
    currently developed protocol, this is normally the latest version.  You can
    see {{!Tezos_protocol_environment_sigs} the full list of versions here}.

    For details on how Protocol and Environment interact, see
    {{:https://tezos.gitlab.io/shell/the_big_picture.html} this overview}.
