434 | Notes: |
435 | Using "-f directory" may give unexpected results: | |
f5492666 JP |
436 | Used with "--git", git signators for _all_ files in and below |
437 | directory are examined as git recurses directories. | |
438 | Any specified X: (exclude) pattern matches are _not_ ignored. | |
439 | Used with "--nogit", directory is used as a pattern match, | |
440 | no individual file within the directory or subdirectory | |
441 | is matched. | |
442 | Used with "--git-blame", does not iterate all files in directory | |
443 | Using "--git-blame" is slow and may add old committers and authors | |
444 | that are no longer active maintainers to the output. | |
3c7385b8 JP |
445 | Using "--roles" or "--rolestats" with git send-email --cc-cmd or any |
446 | other automated tools that expect only ["name"] <email address> | |
447 | may not work because of additional output after <email address>. | |
448 | Using "--rolestats" and "--git-blame" shows the #/total=% commits, | |
449 | not the percentage of the entire file authored. # of commits is | |
450 | not a good measure of amount of code authored. 1 major commit may | |
451 | contain a thousand lines, 5 trivial commits may modify a single line. | |
