994 MAINTAINER field selection options:
995 --email => print email address(es) if any
996 --git => include recent git \*-by: signers
997 --git-all-signature-types => include signers regardless of signature type
998 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
999 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
1000 --git-chief-penguins => include ${penguin_chiefs}
1001 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
1002 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
1003 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
1004 --git-blame => use git blame to find modified commits for patch or file
1005 --git-blame-signatures => when used with --git-blame, also include all commit signers
1006 --git-since => git history to use (default: $email_git_since)
1007 --hg-since => hg history to use (default: $email_hg_since)
1008 --interactive => display a menu (mostly useful if used with the --git option)
1009 --m => include maintainer(s) if any
1010 --r => include reviewer(s) if any
1011 --n => include name 'Full Name <addr\@domain.tld>'
1012 --l => include list(s) if any
1013 --s => include subscriber only list(s) if any
1014 --remove-duplicates => minimize duplicate email names/addresses
1015 --roles => show roles (status:subsystem, git-signer, list, etc...)
1016 --rolestats => show roles and statistics (commits/total_commits, %)
1017 --file-emails => add email addresses found in -f file (default: 0 (off))
1018 --scm => print SCM tree(s) if any
1019 --status => print status if any
1020 --subsystem => print subsystem name if any
1021 --web => print website(s) if any
1023 Output type options:
1024 --separator [, ] => separator for multiple entries on 1 line
1025 using --separator also sets --nomultiline if --separator is not [, ]
1026 --multiline => print 1 entry per line
1029 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
1030 --keywords => scan patch for keywords (default: $keywords)
1031 --sections => print all of the subsystem sections with pattern matches
1032 --letters => print all matching 'letter' types from all matching sections
1033 --mailmap => use .mailmap file (default: $email_use_mailmap)
1034 --self-test => show potential issues with MAINTAINERS file content
1035 --version => show version
1036 --help => show this help information

1040 --remove-duplicates --rolestats]
1043 Using "-f directory" may give unexpected results:
1044 Used with "--git", git signators for _all_ files in and below
1045 directory are examined as git recurses directories.
1046 Any specified X: (exclude) pattern matches are _not_ ignored.
1047 Used with "--nogit", directory is used as a pattern match,
1048 no individual file within the directory or subdirectory
1050 Used with "--git-blame", does not iterate all files in directory
1051 Using "--git-blame" is slow and may add old committers and authors
1052 that are no longer active maintainers to the output.
1053 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
1054 other automated tools that expect only ["name"] <email address>
1055 may not work because of additional output after <email address>.
1056 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
1057 not the percentage of the entire file authored. # of commits is
1058 not a good measure of amount of code authored. 1 major commit may
1059 contain a thousand lines, 5 trivial commits may modify a single line.
1060 If git is not installed, but mercurial (hg) is installed and an .hg
1061 repository exists, the following options apply to mercurial:
1063 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
1065 Use --hg-since not --git-since to control date selection
1066 File ".get_maintainer.conf", if it exists in the linux kernel source root
1067 directory, can change whatever get_maintainer defaults are desired.
1068 Entries in this file can be any command line argument.
1069 This file is prepended to any additional command line arguments.
1070 Multiple lines and # comments are allowed.
1071 Most options have both positive and negative forms.
1072 The negative forms for --<foo> are --no<foo> and --no-<foo>.

1956 If you have git or hg installed, you can choose to summarize the commit
1957 history of files in the patch. Also, each line of the current file can
1958 be matched to its commit author and that commits signers with blame.
1960 Various knobs exist to control the length of time for active commit
1961 tracking, the maximum number of commit authors and signers to add,
