-If the file `.mailmap` exists at the toplevel of the repository, or at
-the location pointed to by the mailmap.file configuration option, it
-is used to map author and committer names and email addresses to
-canonical real names and email addresses.
-This mapping can be used to coalesce together commits by the same
-person where their name and/or email address was spelled differently.
-
-In the simple form, each line in the file consists of the canonical
-real name of an author, whitespace, and an email address used in the
-commit (enclosed by '<' and '>') to map to the name. Thus, looks like
-this
---
-	Proper Name <commit@email.xx>
---
-
-The more complex forms are
---
-	<proper@email.xx> <commit@email.xx>
---
-which allows mailmap to replace only the email part of a commit, and
---
-	Proper Name <proper@email.xx> <commit@email.xx>
---
-which allows mailmap to replace both the name and the email of a
-commit matching the specified commit email address, and
---
-	Proper Name <proper@email.xx> Commit Name <commit@email.xx>
---
-which allows mailmap to replace both the name and the email of a
-commit matching both the specified commit name and email address.

-Example 1: Your history contains commits by two authors, Jane
-and Joe, whose names appear in the repository under several forms:
-
-------------
-Joe Developer <joe@example.com>
-Joe R. Developer <joe@example.com>
-Jane Doe <jane@example.com>
-Jane Doe <jane@laptop.(none)>
-Jane D. <jane@desktop.(none)>
-------------
-
-Now suppose that Joe wants his middle name initial used, and Jane
-prefers her family name fully spelled out. A proper `.mailmap` file
-would look like:
-
-------------
-Jane Doe         <jane@desktop.(none)>
-Joe R. Developer <joe@example.com>
-------------
-
-Note how we don't need an entry for <jane@laptop.(none)>, because the
-real name of that author is correct already, and coalesced directly.
-
-Example 2: Your repository contains commits from the following
-authors:
-
-------------
-nick1 <bugs@company.xx>
-nick2 <bugs@company.xx>
-nick2 <nick2@company.xx>
-santa <me@company.xx>
-claus <me@company.xx>
-CTO <cto@coompany.xx>
-------------
-
-Then, you might want a `.mailmap` file looking like:
-------------
-<cto@company.xx>                       <cto@coompany.xx>
-Some Dude <some@dude.xx>         nick1 <bugs@company.xx>
-Other Author <other@author.xx>   nick2 <bugs@company.xx>
-Other Author <other@author.xx>         <nick2@company.xx>
-Santa Claus <santa.claus@northpole.xx> <me@company.xx>
-------------

-Use hash '#' for comments that are either on their own line, or after
