Common Options
==============

A list of options common to ``create`` and ``modify``

--name NAME
        A name for the torrent file.
        Changing the name will change the checksum of the torrent file so it will be considered a different file.
        On creation if not set, the name will be set to the basename of the specified path.
        The name cannot be unset.
--private, --no-private
        Set/unset the private flag.
        Changing the private flag will change the checksum of the torrent file so it will be considered a different file.
--comment COMMENT, --no-comment
        Set/unset the description of the torrent file.
--created-by CREATED-BY, --no-created-by
        Set/unset the 'created by' field of the torrent file.
        On creation if not set or explicitly unset, it will be set to the CLI tool banner.
--creation-date CREATION-DATE, --no-creation-date
        Set/unset the creation time of the torrent file.
        It can be a UNIX timestamp or `any format that PHP accepts`__.
        RFC 3339 format is recommended (``"2022-06-02T16:58:35+00:00"``).
        On creation if not set or explicitly unset, the current system time will be used.
--announce ANNOUNCE, --no-announce
        Set/unset the announce url of the torrent file.
        (The only or main-ish tracker)
--announce-list ANNOUNCE-LIST, --no-announce-list
        Set/unset the tiered list of announce urls.
        A comma separated list of trackers for a single announce list tier.
        Use multiple times to create multiple tiers.
        If used even once, the old announce list is removed.
