485 MAINTAINER field selection options:
486 --email => print email address(es) if any
487 --git => include recent git \*-by: signers
488 --git-chief-penguins => include ${penguin_chiefs}
489 --git-min-signatures => number of signatures required (default: 1)
490 --git-max-maintainers => maximum maintainers to add (default: 5)
491 --git-min-percent => minimum percentage of commits required (default: 5)
492 --git-blame => use git blame to find modified commits for patch or file
493 --git-since => git history to use (default: 1-year-ago)
494 --hg-since => hg history to use (default: -365)
495 --m => include maintainer(s) if any
496 --n => include name 'Full Name <addr\@domain.tld>'
497 --l => include list(s) if any
498 --s => include subscriber only list(s) if any
499 --remove-duplicates => minimize duplicate email names/addresses
500 --roles => show roles (status:subsystem, git-signer, list, etc...)
501 --rolestats => show roles and statistics (commits/total_commits, %)
502 --file-emails => add email addresses found in -f file (default: 0 (off))
503 --scm => print SCM tree(s) if any
504 --status => print status if any
505 --subsystem => print subsystem name if any
506 --web => print website(s) if any
509 --separator [, ] => separator for multiple entries on 1 line
510 using --separator also sets --nomultiline if --separator is not [, ]
511 --multiline => print 1 entry per line
514 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
515 --keywords => scan patch for keywords (default: 1 (on))
516 --sections => print the entire subsystem sections with pattern matches
517 --version => show version
518 --help => show this help information
521 [--email --git --m --n --l --multiline --pattern-depth=0 --remove-duplicates]
524 Using "-f directory" may give unexpected results:
525 Used with "--git", git signators for _all_ files in and below
526 directory are examined as git recurses directories.
527 Any specified X: (exclude) pattern matches are _not_ ignored.
528 Used with "--nogit", directory is used as a pattern match,
529 no individual file within the directory or subdirectory
531 Used with "--git-blame", does not iterate all files in directory
532 Using "--git-blame" is slow and may add old committers and authors
533 that are no longer active maintainers to the output.
534 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
535 other automated tools that expect only ["name"] <email address>
536 may not work because of additional output after <email address>.
537 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
538 not the percentage of the entire file authored. # of commits is
539 not a good measure of amount of code authored. 1 major commit may
540 contain a thousand lines, 5 trivial commits may modify a single line.
541 If git is not installed, but mercurial (hg) is installed and an .hg
542 repository exists, the following options apply to mercurial:
544 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
546 Use --hg-since not --git-since to control date selection
