728 MAINTAINER field selection options:
729 --email => print email address(es) if any
730 --git => include recent git \*-by: signers
731 --git-all-signature-types => include signers regardless of signature type
732 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
733 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
734 --git-chief-penguins => include ${penguin_chiefs}
735 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
736 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
737 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
738 --git-blame => use git blame to find modified commits for patch or file
739 --git-since => git history to use (default: $email_git_since)
740 --hg-since => hg history to use (default: $email_hg_since)
741 --interactive => display a menu (mostly useful if used with the --git option)
742 --m => include maintainer(s) if any
743 --n => include name 'Full Name <addr\@domain.tld>'
744 --l => include list(s) if any
745 --s => include subscriber only list(s) if any
746 --remove-duplicates => minimize duplicate email names/addresses
747 --roles => show roles (status:subsystem, git-signer, list, etc...)
748 --rolestats => show roles and statistics (commits/total_commits, %)
749 --file-emails => add email addresses found in -f file (default: 0 (off))
750 --scm => print SCM tree(s) if any
751 --status => print status if any
752 --subsystem => print subsystem name if any
753 --web => print website(s) if any
756 --separator [, ] => separator for multiple entries on 1 line
757 using --separator also sets --nomultiline if --separator is not [, ]
758 --multiline => print 1 entry per line
761 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
762 --keywords => scan patch for keywords (default: $keywords)
763 --sections => print all of the subsystem sections with pattern matches
764 --mailmap => use .mailmap file (default: $email_use_mailmap)
765 --version => show version
766 --help => show this help information
769 [--email --nogit --git-fallback --m --n --l --multiline -pattern-depth=0
770 --remove-duplicates --rolestats]
773 Using "-f directory" may give unexpected results:
774 Used with "--git", git signators for _all_ files in and below
775 directory are examined as git recurses directories.
776 Any specified X: (exclude) pattern matches are _not_ ignored.
777 Used with "--nogit", directory is used as a pattern match,
778 no individual file within the directory or subdirectory
780 Used with "--git-blame", does not iterate all files in directory
781 Using "--git-blame" is slow and may add old committers and authors
782 that are no longer active maintainers to the output.
783 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
784 other automated tools that expect only ["name"] <email address>
785 may not work because of additional output after <email address>.
786 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
787 not the percentage of the entire file authored. # of commits is
788 not a good measure of amount of code authored. 1 major commit may
789 contain a thousand lines, 5 trivial commits may modify a single line.
790 If git is not installed, but mercurial (hg) is installed and an .hg
791 repository exists, the following options apply to mercurial:
793 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
795 Use --hg-since not --git-since to control date selection
