```text save 0.5.3 Would you like to SAVE the change?

Commit everything in the current Git repository, no questions asked.

USAGE: save [OPTIONS]

OPTIONS: -a, --name The author name to use for the commit.

        [default: name from git, or else from parent commit, or else
        "save"]

-e, --email <EMAIL>
        The author email to use for the commit.

        [default: email from git, or else from parent commit, or
        else "save"]

-h, --help
        Print help information

-m, --message <MESSAGE>
        Commit message to use.

        [default: generated from generation number, tree hash, and
        parents]

-n, --dry-run
        Prepare the commit, but don't actually save anything to disk

-q, --quiet
        Decrease log verbosity. May be used multiple times

-s, --squash <SQUASH_COMMITS>
        Squash/amend previous commit(s), instead of adding a new
        one.

        By default, `--squash` will behave like `git commit
        --amend`, only replacing the most recent commit. However,
        specifying a larger number such as `--squash=2` will squash
        that many recent commits (and any current changes) into a
        single commit. If any of those commits are merges, any non-
        squashed parents will be added as parents of the squashed
        commit. Any additional authors will be included in Co-
        Authored-By footers.

        [default: 0]

-t, --step <STEP_SECONDS>
        Seconds of timestamp allocated for each commit to search.

        The number of possibilities searched is the half the square
        of this value.

        [default: 128]

-v, --verbose
        Increase log verbosity. May be used multiple times

-V, --version
        Print version information

-w, --now <NOW_SECONDS>
        The time is NOW.

        [default: the time is ACTUALLY now]

-x, --hash <HASH_HEX>
        The target commit hash or prefix, in hex.

        [default: the commit's tree hash]

-y, --yes
        Proceed in spite of any warnings
