729 MAINTAINER field selection options:

732 --git-all-signature-types => include signers regardless of signature type
733 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
734 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
735 --git-chief-penguins => include ${penguin_chiefs}
736 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
737 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
738 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
739 --git-blame => use git blame to find modified commits for patch or file
740 --git-since => git history to use (default: $email_git_since)
741 --hg-since => hg history to use (default: $email_hg_since)
742 --interactive => display a menu (mostly useful if used with the --git option)
743 --m => include maintainer(s) if any
744 --n => include name 'Full Name <addr\@domain.tld>'
745 --l => include list(s) if any
746 --s => include subscriber only list(s) if any
747 --remove-duplicates => minimize duplicate email names/addresses
748 --roles => show roles (status:subsystem, git-signer, list, etc...)
749 --rolestats => show roles and statistics (commits/total_commits, %)
750 --file-emails => add email addresses found in -f file (default: 0 (off))
751 --scm => print SCM tree(s) if any
752 --status => print status if any
753 --subsystem => print subsystem name if any
754 --web => print website(s) if any
757 --separator [, ] => separator for multiple entries on 1 line
758 using --separator also sets --nomultiline if --separator is not [, ]
759 --multiline => print 1 entry per line
762 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
763 --keywords => scan patch for keywords (default: $keywords)
764 --sections => print all of the subsystem sections with pattern matches
765 --mailmap => use .mailmap file (default: $email_use_mailmap)
766 --version => show version
767 --help => show this help information
770 [--email --nogit --git-fallback --m --n --l --multiline -pattern-depth=0

774 Using "-f directory" may give unexpected results:
775 Used with "--git", git signators for _all_ files in and below
776 directory are examined as git recurses directories.
777 Any specified X: (exclude) pattern matches are _not_ ignored.
778 Used with "--nogit", directory is used as a pattern match,
779 no individual file within the directory or subdirectory
781 Used with "--git-blame", does not iterate all files in directory
782 Using "--git-blame" is slow and may add old committers and authors
783 that are no longer active maintainers to the output.
784 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
785 other automated tools that expect only ["name"] <email address>
786 may not work because of additional output after <email address>.
787 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
788 not the percentage of the entire file authored. # of commits is
789 not a good measure of amount of code authored. 1 major commit may
790 contain a thousand lines, 5 trivial commits may modify a single line.
791 If git is not installed, but mercurial (hg) is installed and an .hg
792 repository exists, the following options apply to mercurial:
794 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
796 Use --hg-since not --git-since to control date selection
