<listitem><para>Default release to install packages from if more than one
version is available. Contains release name, codename or release version. Examples: 'stable', 'testing',
<para><literal>Acquire::http::User-Agent</literal> can be used to set a different
User-Agent for the http download method as some proxies allow access for clients
only if the client uses a known identifier.</para>
+
+ <para><literal>Acquire::http::Proxy-Auto-Detect</literal> can be used to
+ specify an external command to discover the http proxy to use. Apt expects
+ the command to output the proxy on stdout in the style
+ <literal>http://proxy:port/</literal>. This will override the
+ generic <literal>Acquire::http::Proxy</literal> but not any specific
+ host proxy configuration set via
+ <literal>Acquire::http::Proxy::$HOST</literal>.
+
+ See the &squid-deb-proxy-client; package for an example implementation that
+ uses avahi. This option takes precedence over the legacy option name
+ <literal>ProxyAutoDetect</literal>.
