760 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)

765 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)

767 --git-since => git history to use (default: $email_git_since)
768 --hg-since => hg history to use (default: $email_hg_since)
769 --interactive => display a menu (mostly useful if used with the --git option)
770 --m => include maintainer(s) if any

801 Using "-f directory" may give unexpected results:
802 Used with "--git", git signators for _all_ files in and below
803 directory are examined as git recurses directories.
804 Any specified X: (exclude) pattern matches are _not_ ignored.
805 Used with "--nogit", directory is used as a pattern match,
806 no individual file within the directory or subdirectory
808 Used with "--git-blame", does not iterate all files in directory
809 Using "--git-blame" is slow and may add old committers and authors
810 that are no longer active maintainers to the output.
811 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
812 other automated tools that expect only ["name"] <email address>
813 may not work because of additional output after <email address>.
814 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
815 not the percentage of the entire file authored. # of commits is
816 not a good measure of amount of code authored. 1 major commit may
817 contain a thousand lines, 5 trivial commits may modify a single line.
818 If git is not installed, but mercurial (hg) is installed and an .hg
819 repository exists, the following options apply to mercurial:
821 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
823 Use --hg-since not --git-since to control date selection
824 File ".get_maintainer.conf", if it exists in the linux kernel source root
825 directory, can change whatever get_maintainer defaults are desired.

1691 Interactive mode allows you to select the various maintainers, submitters,
1692 commit signers and mailing lists that could be CC'd on a patch.
1694 Any *'d entry is selected.
1696 If you have git or hg installed, you can choose to summarize the commit
1697 history of files in the patch. Also, each line of the current file can
1698 be matched to its commit author and that commits signers with blame.
1700 Various knobs exist to control the length of time for active commit
1701 tracking, the maximum number of commit authors and signers to add,
1704 Enter selections at the prompt until you are satisfied that the selected
1705 maintainers are appropriate. You may enter multiple selections separated
1706 by either commas or spaces.
