There are better out-of-tree tools, and this tool is not planned to move
into the core anyway.
No tests either.

-NAME
-----
-git-contacts - List people who might be interested in a set of changes
-
-
-SYNOPSIS
---------
-[verse]
-'git contacts' (<patch>|<range>|<rev>)...
-
-
-DESCRIPTION
------------
-
-Given a set of changes, specified as patch files or revisions, determine people
-who might be interested in those changes. This is done by consulting the
-history of each patch or revision hunk to find people mentioned by commits
-which touched the lines of files under consideration.
-
-Input consists of one or more patch files or revision arguments. A revision
-argument can be a range or a single `<rev>` which is interpreted as
-`<rev>..HEAD`, thus the same revision arguments are accepted as for
-linkgit:git-format-patch[1]. Patch files and revision arguments can be combined
-in the same invocation.
-
-This command can be useful for determining the list of people with whom to
-discuss proposed changes, or for finding the list of recipients to Cc: when
-submitting a patch series via `git send-email`. For the latter case, `git
-contacts` can be used as the argument to `git send-email`'s `--cc-cmd` option.
-
-
-DISCUSSION
-----------
-
-`git blame` is invoked for each hunk in a patch file or revision. For each
-commit mentioned by `git blame`, the commit message is consulted for people who
-authored, reviewed, signed, acknowledged, or were Cc:'d. Once the list of
-participants is known, each person's relevance is computed by considering how
-many commits mentioned that person compared with the total number of commits
-under consideration. The final output consists only of participants who exceed
-a minimum threshold of participation.
-
-
-OUTPUT
-------
-
-For each person of interest, a single line is output, terminated by a newline.
-If the person's name is known, ``Name $$<user@host>$$'' is printed; otherwise
-only ``$$<user@host>$$'' is printed.
-
-
-EXAMPLES
---------
-
-* Consult patch files:
-+
-------------
-$ git contacts feature/*.patch
-------------
-
-* Revision range:
-+
-------------
-$ git contacts R1..R2
-------------
-
-* From a single revision to `HEAD`:
-+
-------------
-$ git contacts origin
-------------
-
-* Helper for `git send-email`:
-+
-------------
-$ git send-email --cc-cmd='git contacts' feature/*.patch
-------------
-
-
-LIMITATIONS
------------
-
-Several conditions controlling a person's significance are currently
-hard-coded, such as minimum participation level (10%), blame date-limiting (5
-years), and `-C` level for detecting moved and copied lines (a single `-C`). In
-the future, these conditions may become configurable.
