1009 MAINTAINER field selection options:
1010 --email => print email address(es) if any
1011 --git => include recent git \*-by: signers
1012 --git-all-signature-types => include signers regardless of signature type
1013 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
1014 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
1015 --git-chief-penguins => include ${penguin_chiefs}
1016 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
1017 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
1018 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
1019 --git-blame => use git blame to find modified commits for patch or file
1020 --git-blame-signatures => when used with --git-blame, also include all commit signers
1021 --git-since => git history to use (default: $email_git_since)
1022 --hg-since => hg history to use (default: $email_hg_since)
1023 --interactive => display a menu (mostly useful if used with the --git option)
1024 --m => include maintainer(s) if any
1025 --r => include reviewer(s) if any
1026 --n => include name 'Full Name <addr\@domain.tld>'
1027 --l => include list(s) if any
1028 --moderated => include moderated lists(s) if any (default: true)
1029 --s => include subscriber only list(s) if any (default: false)
1030 --remove-duplicates => minimize duplicate email names/addresses
1031 --roles => show roles (status:subsystem, git-signer, list, etc...)
1032 --rolestats => show roles and statistics (commits/total_commits, %)
1033 --file-emails => add email addresses found in -f file (default: 0 (off))
1034 --scm => print SCM tree(s) if any
1035 --status => print status if any
1036 --subsystem => print subsystem name if any
1037 --web => print website(s) if any
1039 Output type options:
1040 --separator [, ] => separator for multiple entries on 1 line
1041 using --separator also sets --nomultiline if --separator is not [, ]
1042 --multiline => print 1 entry per line
1045 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
1046 --keywords => scan patch for keywords (default: $keywords)
1047 --sections => print all of the subsystem sections with pattern matches
1048 --letters => print all matching 'letter' types from all matching sections
1049 --mailmap => use .mailmap file (default: $email_use_mailmap)
1050 --no-tree => run without a kernel tree
1051 --self-test => show potential issues with MAINTAINERS file content
1052 --version => show version
1053 --help => show this help information

1057 --pattern-depth=0 --remove-duplicates --rolestats]
1060 Using "-f directory" may give unexpected results:
1061 Used with "--git", git signators for _all_ files in and below
1062 directory are examined as git recurses directories.
1063 Any specified X: (exclude) pattern matches are _not_ ignored.
1064 Used with "--nogit", directory is used as a pattern match,
1065 no individual file within the directory or subdirectory
1067 Used with "--git-blame", does not iterate all files in directory
1068 Using "--git-blame" is slow and may add old committers and authors
1069 that are no longer active maintainers to the output.
1070 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
1071 other automated tools that expect only ["name"] <email address>
1072 may not work because of additional output after <email address>.
1073 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
1074 not the percentage of the entire file authored. # of commits is
1075 not a good measure of amount of code authored. 1 major commit may
1076 contain a thousand lines, 5 trivial commits may modify a single line.
1077 If git is not installed, but mercurial (hg) is installed and an .hg
1078 repository exists, the following options apply to mercurial:
1080 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
1082 Use --hg-since not --git-since to control date selection
1083 File ".get_maintainer.conf", if it exists in the linux kernel source root
1084 directory, can change whatever get_maintainer defaults are desired.
1085 Entries in this file can be any command line argument.
1086 This file is prepended to any additional command line arguments.
1087 Multiple lines and # comments are allowed.
1088 Most options have both positive and negative forms.
1089 The negative forms for --<foo> are --no<foo> and --no-<foo>.

1976 If you have git or hg installed, you can choose to summarize the commit
1977 history of files in the patch. Also, each line of the current file can
1978 be matched to its commit author and that commits signers with blame.
1980 Various knobs exist to control the length of time for active commit
1981 tracking, the maximum number of commit authors and signers to add,
