+Long: socks5
+Arg: <host[:port]>
+Help: SOCKS5 proxy on given host + port
+Added: 7.18.0
+---
+Use the specified SOCKS5 proxy - but resolve the host name locally. If the
+port number is not specified, it is assumed at port 1080.
+
+This option overrides any previous use of --proxy, as they are mutually
+exclusive.
+
+Since 7.21.7, this option is superfluous since you can specify a socks5 proxy
+with --proxy using a socks5:// protocol prefix.
+
+Since 7.52.0, --preproxy can be used to specify a SOCKS proxy at the same time
+--proxy is used with an HTTP/HTTPS proxy. In such a case curl first connects to
+the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy.
+
+If this option is used several times, the last one will be used.
+
+This option (as well as --socks4) does not work with IPV6, FTPS or LDAP.
