348 | Notes: |
349 | Using "-f directory" may give unexpected results: | |
f5492666 JP |
350 | Used with "--git", git signators for _all_ files in and below |
351 | directory are examined as git recurses directories. | |
352 | Any specified X: (exclude) pattern matches are _not_ ignored. | |
353 | Used with "--nogit", directory is used as a pattern match, | |
354 | no individual file within the directory or subdirectory | |
355 | is matched. | |
356 | Used with "--git-blame", does not iterate all files in directory | |
357 | Using "--git-blame" is slow and may add old committers and authors | |
358 | that are no longer active maintainers to the output. | |
