+Do not work around a security flaw in the TLS1.0 protocol known as BEAST. If
+this option is not used, the TLS layer may use workarounds known to cause
+interoperability problems with some older server implementations.
+
+This option only changes how curl does TLS 1.0 and has no effect on later TLS
+versions.
+
+**WARNING**: this option loosens the TLS security, and by using this flag you
+ask for exactly that.
