1039 MAINTAINER field selection options:
1040 --email => print email address(es) if any
1041 --git => include recent git \*-by: signers
1042 --git-all-signature-types => include signers regardless of signature type
1043 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
1044 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
1045 --git-chief-penguins => include ${penguin_chiefs}
1046 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
1047 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
1048 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
1049 --git-blame => use git blame to find modified commits for patch or file
1050 --git-blame-signatures => when used with --git-blame, also include all commit signers
1051 --git-since => git history to use (default: $email_git_since)
1052 --hg-since => hg history to use (default: $email_hg_since)
1053 --interactive => display a menu (mostly useful if used with the --git option)
1054 --m => include maintainer(s) if any
1055 --r => include reviewer(s) if any
1056 --n => include name 'Full Name <addr\@domain.tld>'
1057 --l => include list(s) if any
1058 --moderated => include moderated lists(s) if any (default: true)
1059 --s => include subscriber only list(s) if any (default: false)
1060 --remove-duplicates => minimize duplicate email names/addresses
1061 --roles => show roles (status:subsystem, git-signer, list, etc...)
1062 --rolestats => show roles and statistics (commits/total_commits, %)
1063 --file-emails => add email addresses found in -f file (default: 0 (off))
1064 --fixes => for patches, add signatures of commits with 'Fixes: <commit>' (default: 1 (on))
1065 --scm => print SCM tree(s) if any
1066 --status => print status if any
1067 --subsystem => print subsystem name if any
1068 --web => print website(s) if any
1070 Output type options:
1071 --separator [, ] => separator for multiple entries on 1 line
1072 using --separator also sets --nomultiline if --separator is not [, ]
1073 --multiline => print 1 entry per line
1076 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
1077 --keywords => scan patch for keywords (default: $keywords)
1078 --sections => print all of the subsystem sections with pattern matches
1079 --letters => print all matching 'letter' types from all matching sections
1080 --mailmap => use .mailmap file (default: $email_use_mailmap)
1081 --no-tree => run without a kernel tree
1082 --self-test => show potential issues with MAINTAINERS file content
1083 --version => show version
1084 --help => show this help information
1087 [--email --tree --nogit --git-fallback --m --r --n --l --multiline
1088 --pattern-depth=0 --remove-duplicates --rolestats]
1091 Using "-f directory" may give unexpected results:
1092 Used with "--git", git signators for _all_ files in and below
1093 directory are examined as git recurses directories.
1094 Any specified X: (exclude) pattern matches are _not_ ignored.
1095 Used with "--nogit", directory is used as a pattern match,
1096 no individual file within the directory or subdirectory
1098 Used with "--git-blame", does not iterate all files in directory
1099 Using "--git-blame" is slow and may add old committers and authors
1100 that are no longer active maintainers to the output.
1101 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
1102 other automated tools that expect only ["name"] <email address>
1103 may not work because of additional output after <email address>.
1104 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
1105 not the percentage of the entire file authored. # of commits is
1106 not a good measure of amount of code authored. 1 major commit may
1107 contain a thousand lines, 5 trivial commits may modify a single line.
1108 If git is not installed, but mercurial (hg) is installed and an .hg
1109 repository exists, the following options apply to mercurial:
1111 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
1113 Use --hg-since not --git-since to control date selection
1114 File ".get_maintainer.conf", if it exists in the linux kernel source root
1115 directory, can change whatever get_maintainer defaults are desired.
1116 Entries in this file can be any command line argument.
1117 This file is prepended to any additional command line arguments.
1118 Multiple lines and # comments are allowed.
1119 Most options have both positive and negative forms.
1120 The negative forms for --<foo> are --no<foo> and --no-<foo>.

2007 Any *'d entry is selected.
2009 If you have git or hg installed, you can choose to summarize the commit
2010 history of files in the patch. Also, each line of the current file can
2011 be matched to its commit author and that commits signers with blame.
2013 Various knobs exist to control the length of time for active commit
2014 tracking, the maximum number of commit authors and signers to add,
