602 | Notes: |
603 | Using "-f directory" may give unexpected results: | |
f5492666 JP |
604 | Used with "--git", git signators for _all_ files in and below |
605 | directory are examined as git recurses directories. | |
606 | Any specified X: (exclude) pattern matches are _not_ ignored. | |
607 | Used with "--nogit", directory is used as a pattern match, | |
60db31ac JP |
608 | no individual file within the directory or subdirectory |
609 | is matched. | |
f5492666 JP |
610 | Used with "--git-blame", does not iterate all files in directory |
611 | Using "--git-blame" is slow and may add old committers and authors | |
612 | that are no longer active maintainers to the output. | |
3c7385b8 JP |
613 | Using "--roles" or "--rolestats" with git send-email --cc-cmd or any |
614 | other automated tools that expect only ["name"] <email address> | |
615 | may not work because of additional output after <email address>. | |
616 | Using "--rolestats" and "--git-blame" shows the #/total=% commits, | |
617 | not the percentage of the entire file authored. # of commits is | |
618 | not a good measure of amount of code authored. 1 major commit may | |
619 | contain a thousand lines, 5 trivial commits may modify a single line. | |
60db31ac JP |
620 | If git is not installed, but mercurial (hg) is installed and an .hg |
621 | repository exists, the following options apply to mercurial: | |
622 | --git, | |
623 | --git-min-signatures, --git-max-maintainers, --git-min-percent, and | |
624 | --git-blame | |
625 | Use --hg-since not --git-since to control date selection | |
