Joe Perches870020f2009-07-29 15:04:28 -0700535Notes:
536 Using "-f directory" may give unexpected results:
Joe Perchesf5492662009-09-21 17:04:13 -0700537 Used with "--git", git signators for _all_ files in and below
538 directory are examined as git recurses directories.
539 Any specified X: (exclude) pattern matches are _not_ ignored.
540 Used with "--nogit", directory is used as a pattern match,
Joe Perches60db31a2009-12-14 18:00:50 -0800541 no individual file within the directory or subdirectory
542 is matched.
Joe Perchesf5492662009-09-21 17:04:13 -0700543 Used with "--git-blame", does not iterate all files in directory
544 Using "--git-blame" is slow and may add old committers and authors
545 that are no longer active maintainers to the output.
Joe Perches3c7385b2009-12-14 18:00:46 -0800546 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
547 other automated tools that expect only ["name"] <email address>
548 may not work because of additional output after <email address>.
549 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
550 not the percentage of the entire file authored. # of commits is
551 not a good measure of amount of code authored. 1 major commit may
552 contain a thousand lines, 5 trivial commits may modify a single line.
Joe Perches60db31a2009-12-14 18:00:50 -0800553 If git is not installed, but mercurial (hg) is installed and an .hg
554 repository exists, the following options apply to mercurial:
555 --git,
556 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
557 --git-blame
558 Use --hg-since not --git-since to control date selection
