738 MAINTAINER field selection options:
739 --email => print email address(es) if any
740 --git => include recent git \*-by: signers
741 --git-all-signature-types => include signers regardless of signature type
742 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
743 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
744 --git-chief-penguins => include ${penguin_chiefs}
745 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
746 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
747 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
748 --git-blame => use git blame to find modified commits for patch or file
749 --git-since => git history to use (default: $email_git_since)
750 --hg-since => hg history to use (default: $email_hg_since)
751 --interactive => display a menu (mostly useful if used with the --git option)
752 --m => include maintainer(s) if any
753 --n => include name 'Full Name <addr\@domain.tld>'
754 --l => include list(s) if any
755 --s => include subscriber only list(s) if any
756 --remove-duplicates => minimize duplicate email names/addresses
757 --roles => show roles (status:subsystem, git-signer, list, etc...)
758 --rolestats => show roles and statistics (commits/total_commits, %)
759 --file-emails => add email addresses found in -f file (default: 0 (off))
760 --scm => print SCM tree(s) if any
761 --status => print status if any
762 --subsystem => print subsystem name if any
763 --web => print website(s) if any
766 --separator [, ] => separator for multiple entries on 1 line
767 using --separator also sets --nomultiline if --separator is not [, ]
768 --multiline => print 1 entry per line
771 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
772 --keywords => scan patch for keywords (default: $keywords)
773 --sections => print all of the subsystem sections with pattern matches
774 --mailmap => use .mailmap file (default: $email_use_mailmap)
775 --version => show version
776 --help => show this help information
779 [--email --nogit --git-fallback --m --n --l --multiline -pattern-depth=0
780 --remove-duplicates --rolestats]
783 Using "-f directory" may give unexpected results:
784 Used with "--git", git signators for _all_ files in and below
785 directory are examined as git recurses directories.
786 Any specified X: (exclude) pattern matches are _not_ ignored.
787 Used with "--nogit", directory is used as a pattern match,
788 no individual file within the directory or subdirectory
790 Used with "--git-blame", does not iterate all files in directory
791 Using "--git-blame" is slow and may add old committers and authors
792 that are no longer active maintainers to the output.
793 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
794 other automated tools that expect only ["name"] <email address>
795 may not work because of additional output after <email address>.
796 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
797 not the percentage of the entire file authored. # of commits is
798 not a good measure of amount of code authored. 1 major commit may
799 contain a thousand lines, 5 trivial commits may modify a single line.
800 If git is not installed, but mercurial (hg) is installed and an .hg
801 repository exists, the following options apply to mercurial:
803 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
805 Use --hg-since not --git-since to control date selection

1678 be matched to its commit author and that commits signers with blame.
1680 Various knobs exist to control the length of time for active commit
1681 tracking, the maximum number of commit authors and signers to add,
1684 Enter selections at the prompt until you are satisfied that the selected
1685 maintainers are appropriate. You may enter multiple selections separated
