>>> + 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 + that are no longer active maintainers to the output.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
