1094Notes:
1095 Using "-f directory" may give unexpected results:
1096 Used with "--git", git signators for _all_ files in and below
1097 directory are examined as git recurses directories.
1098 Any specified X: (exclude) pattern matches are _not_ ignored.
1099 Used with "--nogit", directory is used as a pattern match,
1100 no individual file within the directory or subdirectory
1101 is matched.
1102 Used with "--git-blame", does not iterate all files in directory
1103 Using "--git-blame" is slow and may add old committers and authors
1104 that are no longer active maintainers to the output.
1105 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
1106 other automated tools that expect only ["name"] <email address>
1107 may not work because of additional output after <email address>.
1108 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
1109 not the percentage of the entire file authored. # of commits is
1110 not a good measure of amount of code authored. 1 major commit may
1111 contain a thousand lines, 5 trivial commits may modify a single line.
1112 If git is not installed, but mercurial (hg) is installed and an .hg
1113 repository exists, the following options apply to mercurial:
1114 --git,
1115 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
1116 --git-blame
1117 Use --hg-since not --git-since to control date selection
1118 File ".get_maintainer.conf", if it exists in the linux kernel source root
1119 directory, can change whatever get_maintainer defaults are desired.
1120 Entries in this file can be any command line argument.
1121 This file is prepended to any additional command line arguments.
1122 Multiple lines and # comments are allowed.
1123 Most options have both positive and negative forms.
1124 The negative forms for --<foo> are --no<foo> and --no-<foo>.

1049 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
1050 --git-blame => use git blame to find modified commits for patch or file
1051 --git-blame-signatures => when used with --git-blame, also include all commit signers
1052 --git-since => git history to use (default: $email_git_since)
1053 --hg-since => hg history to use (default: $email_hg_since)
1054 --interactive => display a menu (mostly useful if used with the --git option)
1055 --m => include maintainer(s) if any

1070
1071Output type options:
1072 --separator [, ] => separator for multiple entries on 1 line
1073 using --separator also sets --nomultiline if --separator is not [, ]

1075
1076Other options:
1077 --pattern-depth => Number of pattern directory traversals (default: 0 (all))

1090
1091Notes:
1092 Using "-f directory" may give unexpected results:
1093 Used with "--git", git signators for _all_ files in and below
1094 directory are examined as git recurses directories.
1095 Any specified X: (exclude) pattern matches are _not_ ignored.
1096 Used with "--nogit", directory is used as a pattern match,
1097 no individual file within the directory or subdirectory
1098 is matched.
1099 Used with "--git-blame", does not iterate all files in directory
1100 Using "--git-blame" is slow and may add old committers and authors
1101 that are no longer active maintainers to the output.
1102 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
1103 other automated tools that expect only ["name"] <email address>
1104 may not work because of additional output after <email address>.
1105 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
1106 not the percentage of the entire file authored. # of commits is
1107 not a good measure of amount of code authored. 1 major commit may
1108 contain a thousand lines, 5 trivial commits may modify a single line.
1109 If git is not installed, but mercurial (hg) is installed and an .hg
1110 repository exists, the following options apply to mercurial:
1111 --git,
1112 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
1113 --git-blame
1114 Use --hg-since not --git-since to control date selection
1115 File ".get_maintainer.conf", if it exists in the linux kernel source root
1116 directory, can change whatever get_maintainer defaults are desired.
1117 Entries in this file can be any command line argument.
1118 This file is prepended to any additional command line arguments.
1119 Multiple lines and # comments are allowed.
1120 Most options have both positive and negative forms.
1121 The negative forms for --<foo> are --no<foo> and --no-<foo>.
