>>> + Used with "--git-blame", does not iterate all files in directory
>>> + Using "--git-blame" is slow and may add old committers and authors

>>> + 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 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
