  863. --git => include recent git \*-by: signers
  864. --git-all-signature-types => include signers regardless of signature type
  865. or use only ${signature_pattern} signers (default: $email_git_all_signature_types)

  870. --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
  871. --git-blame => use git blame to find modified commits for patch or file
  872. --git-blame-signatures => when used with --git-blame, also include all commit signers
  873. --git-since => git history to use (default: $email_git_since)
  874. --hg-since => hg history to use (default: $email_hg_since)
  875. --interactive => display a menu (mostly useful if used with the --git option)
  876. --m => include maintainer(s) if any
  877. --r => include reviewer(s) if any
  878. --n => include name 'Full Name <addr\@domain.tld>'

  885. --scm => print SCM tree(s) if any
  886. --status => print status if any
  887. --subsystem => print subsystem name if any
  888. --web => print website(s) if any
  889. Output type options:
  890. --separator [, ] => separator for multiple entries on 1 line
  891. using --separator also sets --nomultiline if --separator is not [, ]
  892. --multiline => print 1 entry per line
  893. Other options:
  894. --pattern-depth => Number of pattern directory traversals (default: 0 (all))
  895. --keywords => scan patch for keywords (default: $keywords)
  896. --sections => print all of the subsystem sections with pattern matches
  897. --letters => print all matching 'letter' types from all matching sections
  898. --mailmap => use .mailmap file (default: $email_use_mailmap)
  899. --self-test => show potential issues with MAINTAINERS file content
  900. --version => show version
  901. --help => show this help information
  902. Default options:
  903. [--email --nogit --git-fallback --m --r --n --l --multiline --pattern-depth=0
  904. --remove-duplicates --rolestats]
  905. Notes:
  906. Using "-f directory" may give unexpected results:
  907. Used with "--git", git signators for _all_ files in and below
  908. directory are examined as git recurses directories.
  909. Any specified X: (exclude) pattern matches are _not_ ignored.
  910. Used with "--nogit", directory is used as a pattern match,
  911. no individual file within the directory or subdirectory
  912. is matched.
  913. Used with "--git-blame", does not iterate all files in directory
  914. Using "--git-blame" is slow and may add old committers and authors
  915. that are no longer active maintainers to the output.
  916. Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
  917. other automated tools that expect only ["name"] <email address>
  918. may not work because of additional output after <email address>.
  919. Using "--rolestats" and "--git-blame" shows the #/total=% commits,
  920. not the percentage of the entire file authored. # of commits is
  921. not a good measure of amount of code authored. 1 major commit may
  922. contain a thousand lines, 5 trivial commits may modify a single line.
  923. If git is not installed, but mercurial (hg) is installed and an .hg
  924. repository exists, the following options apply to mercurial:
  925. --git,
  926. --git-min-signatures, --git-max-maintainers, --git-min-percent, and
  927. --git-blame
  928. Use --hg-since not --git-since to control date selection
  929. File ".get_maintainer.conf", if it exists in the linux kernel source root
  930. directory, can change whatever get_maintainer defaults are desired.
  931. Entries in this file can be any command line argument.
  932. This file is prepended to any additional command line arguments.
  933. Multiple lines and # comments are allowed.
  934. Most options have both positive and negative forms.
  935. The negative forms for --<foo> are --no<foo> and --no-<foo>.
