 | |
|     --s => include subscriber only list(s) if any
 | |
|     --remove-duplicates => minimize duplicate email names/addresses
 | |
|     --roles => show roles (status:subsystem, git-signer, list, etc...)
 | |
|     --rolestats => show roles and statistics (commits/total_commits, %)
 | |
|   --scm => print SCM tree(s) if any
 | |
|   --status => print status if any
 | |
|   --subsystem => print subsystem name if any
 | |
|   --web => print website(s) if any
 | |
| 
 | |
| Output type options:
 | |
|   --separator [, ] => separator for multiple entries on 1 line
 | |
|     using --separator also sets --nomultiline if --separator is not [, ]
 | |
|   --multiline => print 1 entry per line
 | |
| 
 | |
| Other options:
 | |
|   --pattern-depth => Number of pattern directory traversals (default: 0 (all))
 | |
|   --keywords => scan patch for keywords (default: 1 (on))
 | |
|   --version => show version
 | |
|   --help => show this help information
 | |
| 
 | |
| Default options:
 | |
|   [--email --git --m --n --l --multiline --pattern-depth=0 --remove-duplicates]
 | |
| 
 | |
| Notes:
 | |
|   Using "-f directory" may give unexpected results:
 | |
|       Used with "--git", git signators for _all_ files in and below
 | |
|           directory are examined as git recurses directories.
 | |
|           Any specified X: (exclude) pattern matches are _not_ ignored.
 | |
|       Used with "--nogit", directory is used as a pattern match,
 | |
|           no individual file within the directory or subdirectory
 | |
|           is matched.
 | |
|       Used with "--git-blame", does not iterate all files in directory
 | |
|   Using "--git-blame" is slow and may add old committers and authors
 | |
|       that are no longer active maintainers to the output.
 | |
|   Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
 | |
|       other automated tools that expect only ["name"] <email address>
 | |
|       may not work because of additional output after <email address>.
 | |
|   Using "--rolestats" and "--git-blame" shows the #/total=% commits,
 | |
|       not the percentage of the entire file authored.  # of commits is
 | |
|       not a good measure of amount of code authored.  1 major commit may
 | |
|       contain a thousand lines, 5 trivial commits may modify a single line.
 | |
|   If git is not installed, but mercurial (hg) is installed and an .hg
 | |
|       repository exists, the following options apply to mercurial:
 | |
|           --git,
 | |
|           --git-min-signatures, --git-max-maintainers, --git-min-percent, and
 | |
|           --git-blame
 | |
|       Use --hg-since not --git-since to control date selection
