-    Per-repository configuration options that only apply in a
-    particular repository. This file is not version-controlled, and
-    will not get transferred during a "clone" operation. Options in
-    this file override options in all other configuration files. On
-    Plan 9 and Unix, most of this file will be ignored if it doesn't
-    belong to a trusted user or to a trusted group. See the documentation
-    for the ``[trusted]`` section below for more details.
+  On Unix, the following files are consulted:

-| (Unix) ``$HOME/.hgrc``
-| (Windows) ``%USERPROFILE%\.hgrc``
-| (Windows) ``%USERPROFILE%\Mercurial.ini``

-    Per-user configuration file(s), for the user running Mercurial. On
-    Windows 9x, ``%HOME%`` is replaced by ``%APPDATA%``. Options in these
-    files apply to all Mercurial commands executed by this user in any
-    directory. Options in these files override per-system and per-installation
-    options.

-    Per-system configuration files, for the system on which Mercurial
-    is running. Options in these files apply to all Mercurial commands
-    executed by any user in any directory. Options in these files
-    override per-installation options.

+  On Windows, the following files are consulted:
 
-    Per-installation configuration files, searched for in the
-    directory where Mercurial is installed. ``<install-root>`` is the
-    parent directory of the **hg** executable (or symlink) being run. For
-    example, if installed in ``/shared/tools/bin/hg``, Mercurial will look
-    in ``/shared/tools/etc/mercurial/hgrc``. Options in these files apply
-    to all Mercurial commands executed by any user in any directory.
+  - ``<repo>/.hg/hgrc`` (per-repository)

-| (Windows) ``<install-dir>\hgrc.d\*.rc`` **or**
-| (Windows) ``HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial``
-
-    Per-installation/system configuration files, for the system on
-    which Mercurial is running. Options in these files apply to all
-    Mercurial commands executed by any user in any directory. Registry
-    keys contain PATH-like strings, every part of which must reference
-    a ``Mercurial.ini`` file or be a directory where ``*.rc`` files will
-    be read.  Mercurial checks each of these locations in the specified
-    order until one or more configuration files are detected.
