      <summary>Proxy configuration mode</summary>
      <description>
        Select the proxy configuration mode. Supported values are “none”,
        “manual”, “auto”.

If this is “none”, then proxies are not used.

If it is “auto”, the autoconfiguration URL described by the
        “autoconfig-url” key is used.

If it is “manual”, then the proxies described by
        “/system/proxy/http”, “/system/proxy/https”,
        “/system/proxy/ftp” and “/system/proxy/socks” will be used.
        Each of the 4 proxy types is enabled if its “host” key is
        non-empty and its “port” key is non-0.

If an http proxy is configured, but an https proxy is not,
        then the http proxy is also used for https.

If a SOCKS proxy is configured, it is used for all protocols,
        except that the http, https, and ftp proxy settings override
        it for those protocols only.

      <summary>Automatic proxy configuration URL</summary>
      <description>
        URL that provides proxy configuration values. When mode is
        “auto”, this URL is used to look up proxy information for all
        protocols.

      <summary>Non-proxy hosts</summary>
      <description>
        This key contains a list of hosts which are connected to directly,
        rather than via the proxy (if it is active). The values can be
        hostnames, domains (using an initial wildcard like *.foo.com), IP host
        addresses (both IPv4 and IPv6) and network addresses with a netmask
        (something like 192.168.0.0/24).

      <description>
        This key is not used; HTTP proxying is enabled when the host
        key is non-empty and the port is non-0.

      <default>false</default>
      <summary>Authenticate proxy server connections</summary>
      <description>
        If true, then connections to the proxy server require authentication.
        The username/password combo is defined by
        “/system/proxy/http/authentication-user” and
        “/system/proxy/http/authentication-password”.

This applies only to the http proxy; when using a separate
        https proxy, there is currently no way to specify that it
        should use authentication.
