+long: ssl
+Help: Try SSL/TLS
+Protocols: FTP IMAP POP3 SMTP
+Added: 7.20.0
+---
+
+Try to use SSL/TLS for the connection.  Reverts to a non-secure connection if
+the server doesn't support SSL/TLS.  See also --ftp-ssl-control and --ssl-reqd
+for different levels of encryption required.
+
+This option was formerly known as --ftp-ssl (Added in 7.11.0). That option
+name can still be used but will be removed in a future version.
