I assume it was talking about order of subsystems, but maybe reviewers
within subsystem should be sorted too.. I don't think it is *that*
important (and I can drop the note, it was just copied from
$linux/MAINTAINERS), since we don't have quite the level of churn as
the linux kernel.

>> +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 + that are no longer active maintainers to the output.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
>> + File ".get_maintainer.conf", if it exists in the linux kernel source root
>> + directory, can change whatever get_maintainer defaults are desired.
>> + Entries in this file can be any command line argument.
>> + This file is prepended to any additional command line arguments.
>> + Multiple lines and # comments are allowed.
