+    <title>Description</title>
+    <para>This is a configuration file for NetworkManager. It is used
+    to set up various aspects of NetworkManager's behavior. The
+    location of the file may be changed through use of the
+    <option>--config</option> argument for NetworkManager.
+    </para>
+    <para>If a default <literal>NetworkManager.conf</literal> is
+    provided by your distribution's packages, you should not modify
+    it, since your changes may get overwritten by package
+    updates. Instead, you can add additional <literal>.conf</literal>
+    files to the <literal>conf.d</literal> directory. These will be read in order,
+    with later files overriding earlier ones.
+    </para>
+
+  </refsect1>
+
+  <refsect1>
+    <title>File Format</title>
+    <para>
+      The configuration file format is so-called key file (sort of
+      ini-style format).  It consists of sections (groups) of
+      key-value pairs. Lines beginning with a '#' and blank lines are
+      considered comments. Sections are started by a header line
+      containing the section enclosed in '[' and ']', and ended
+      implicitly by the start of the next section or the end of the
+      file. Each key-value pair must be contained in a section.
+    </para>
+    <para>
+      For keys that take a list of devices as their value, you can
+      specify devices by their MAC addresses or interface names, or
+      "*" to specify all devices.
+    </para>
+    <para>
+      Minimal system settings configuration file looks like this:
+      <programlisting>
+	[main]
+	plugins=keyfile
+      </programlisting>
+    </para>
+    <para>
+      As an extension to the normal keyfile format, you can also
+      append a value to a previously-set list-valued key by doing:
+      <programlisting>
+	plugins+=another-plugin
+      </programlisting>
+    </para>
+  </refsect1>

+    <title><literal>main</literal> section</title>
+    <variablelist>
+      <varlistentry>
+	<term><varname>plugins</varname></term>
+	<listitem>
+	  <para>
+	    Lists system settings plugin names separated by ','. These
+	    plugins are used to read and write system-wide
+	    connections. When multiple plugins are specified, the
+	    connections are read from all listed plugins. When writing
+	    connections, the plugins will be asked to save the
+	    connection in the order listed here; if the first plugin
+	    cannot write out that connection type (or can't write out
+	    any connections) the next plugin is tried, etc. If none of
+	    the plugins can save the connection, an error is returned
+	    to the user.
+	  </para>
+	  <para>
+	    If NetworkManager defines a distro-specific
+	    network-configuration plugin for your system, then that
+	    will normally be listed here. (See below for the available
+	    plugins.) Note that the <literal>keyfile</literal> plugin
+	    is always appended to the end of this list (if it doesn't
+	    already appear earlier in the list), so if there is no
+	    distro-specific plugin for your system then you can leave
+	    this key unset and NetworkManager will fall back to using
+	    <literal>keyfile</literal>.

+	<listitem>
+	  <para>
+	    Comma-separated list of devices for which NetworkManager
+	    will (partially) ignore the carrier state. Normally, for
+	    device types that support carrier-detect, such as Ethernet
+	    and InfiniBand, NetworkManager will only allow a
+	    connection to be activated on the device if carrier is
+	    present (ie, a cable is plugged in), and it will
+	    deactivate the device if carrier drops for more than a few
+	    seconds.
+	  </para>
+	  <para>
+	    Listing a device here will allow activating connections on
+	    that device even when it does not have carrier, provided
+	    that the connection uses only statically-configured IP
+	    addresses. Additionally, it will allow any active
+	    connection (whether static or dynamic) to remain active on
+	    the device when carrier is lost.
+	  </para>
+	  <para>
+	    May have the special value <literal>*</literal> to apply
+	    to all devices.
+	  </para>
+	  <para>
+	    Note that the "carrier" property of NMDevices and device D-Bus
+	    interfaces will still reflect the actual device state; it's just
+	    that NetworkManager will not make use of that information.

+	<term><varname>configure-and-quit</varname></term>
+	<listitem>
+	  <para>
+	    When set to <literal>true</literal>, NetworkManager quits after
+	    performing initial network configuration but spawns small helpers
+	    to preserve DHCP leases and IPv6 addresses.  This is useful in
+	    environments where network setup is more or less static or it is
+	    desirable to save process time but still handle some dynamic
+	    configurations.  When this option is <literal>true</literal>,
+	    network configuration for WiFi, WWAN, Bluetooth, ADSL, and PPPoE
+	    interfaces cannot be preserved due to their use of external
+	    services, and these devices will be deconfigured when NetworkManager
+	    quits even though other interface's configuration may be preserved.
+	    The default value is <literal>false</literal>, meaning that
+	    NetworkManager will continue running after initial network
+	    configuration and continue responding to system and hardware events,
+	    D-Bus requests, and user commands.

+	    supports reading Ethernet and Wi-Fi connections, but does
+	    not support saving any connection types.
