578 | Notes: |
579 | Using "-f directory" may give unexpected results: | |
f5492666 JP |
580 | Used with "--git", git signators for _all_ files in and below |
581 | directory are examined as git recurses directories. | |
582 | Any specified X: (exclude) pattern matches are _not_ ignored. | |
583 | Used with "--nogit", directory is used as a pattern match, | |
60db31ac JP |
584 | no individual file within the directory or subdirectory |
585 | is matched. | |
f5492666 JP |
586 | Used with "--git-blame", does not iterate all files in directory |
587 | Using "--git-blame" is slow and may add old committers and authors | |
588 | that are no longer active maintainers to the output. | |
3c7385b8 JP |
589 | Using "--roles" or "--rolestats" with git send-email --cc-cmd or any |
590 | other automated tools that expect only ["name"] <email address> | |
591 | may not work because of additional output after <email address>. | |
592 | Using "--rolestats" and "--git-blame" shows the #/total=% commits, | |
593 | not the percentage of the entire file authored. # of commits is | |
594 | not a good measure of amount of code authored. 1 major commit may | |
595 | contain a thousand lines, 5 trivial commits may modify a single line. | |
60db31ac JP |
596 | If git is not installed, but mercurial (hg) is installed and an .hg |
597 | repository exists, the following options apply to mercurial: | |
598 | --git, | |
599 | --git-min-signatures, --git-max-maintainers, --git-min-percent, and | |
600 | --git-blame | |
601 | Use --hg-since not --git-since to control date selection | |
368669da JP |
602 | File ".get_maintainer.conf", if it exists in the linux kernel source root |
603 | directory, can change whatever get_maintainer defaults are desired. | |
604 | Entries in this file can be any command line argument. | |
605 | This file is prepended to any additional command line arguments. | |
