756MAINTAINER field selection options:
757 --email => print email address(es) if any
758 --git => include recent git \*-by: signers
759 --git-all-signature-types => include signers regardless of signature type
760 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
761 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
762 --git-chief-penguins => include ${penguin_chiefs}
763 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
764 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
765 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
766 --git-blame => use git blame to find modified commits for patch or file
767 --git-since => git history to use (default: $email_git_since)
768 --hg-since => hg history to use (default: $email_hg_since)
769 --interactive => display a menu (mostly useful if used with the --git option)
770 --m => include maintainer(s) if any
771 --n => include name 'Full Name <addr\@domain.tld>'
772 --l => include list(s) if any
773 --s => include subscriber only list(s) if any
774 --remove-duplicates => minimize duplicate email names/addresses
775 --roles => show roles (status:subsystem, git-signer, list, etc...)
776 --rolestats => show roles and statistics (commits/total_commits, %)
777 --file-emails => add email addresses found in -f file (default: 0 (off))

781 --web => print website(s) if any
782
783Output type options:
784 --separator [, ] => separator for multiple entries on 1 line
785 using --separator also sets --nomultiline if --separator is not [, ]
786 --multiline => print 1 entry per line
787
788Other options:
789 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
790 --keywords => scan patch for keywords (default: $keywords)
791 --sections => print all of the subsystem sections with pattern matches
792 --mailmap => use .mailmap file (default: $email_use_mailmap)
793 --version => show version
794 --help => show this help information
795
796Default options:
797 [--email --nogit --git-fallback --m --n --l --multiline -pattern-depth=0
798 --remove-duplicates --rolestats]

800Notes:
801 Using "-f directory" may give unexpected results:
802 Used with "--git", git signators for _all_ files in and below
803 directory are examined as git recurses directories.
804 Any specified X: (exclude) pattern matches are _not_ ignored.
805 Used with "--nogit", directory is used as a pattern match,
806 no individual file within the directory or subdirectory
807 is matched.
808 Used with "--git-blame", does not iterate all files in directory
809 Using "--git-blame" is slow and may add old committers and authors
810 that are no longer active maintainers to the output.
811 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
812 other automated tools that expect only ["name"] <email address>
813 may not work because of additional output after <email address>.
814 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
815 not the percentage of the entire file authored. # of commits is
816 not a good measure of amount of code authored. 1 major commit may
817 contain a thousand lines, 5 trivial commits may modify a single line.
818 If git is not installed, but mercurial (hg) is installed and an .hg
819 repository exists, the following options apply to mercurial:
820 --git,
821 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
822 --git-blame
823 Use --hg-since not --git-since to control date selection
824 File ".get_maintainer.conf", if it exists in the linux kernel source root
825 directory, can change whatever get_maintainer defaults are desired.
826 Entries in this file can be any command line argument.
827 This file is prepended to any additional command line arguments.
