+Long: proto
+Arg: <protocols>
+Help: Enable/disable PROTOCOLS
+See-also: proto-redir proto-default
+Added: 7.20.2
+---
+Tells curl to limit what protocols it may use in the transfer. Protocols are
+evaluated left to right, are comma separated, and are each a protocol name or
+'all', optionally prefixed by zero or more modifiers. Available modifiers are:
+.RS
+.TP 3
+.B +
+Permit this protocol in addition to protocols already permitted (this is
+the default if no modifier is used).
+.TP
+.B -
+Deny this protocol, removing it from the list of protocols already permitted.
+.TP
+.B =
+Permit only this protocol (ignoring the list already permitted), though
+subject to later modification by subsequent entries in the comma separated
+list.
+.RE
+.IP
+For example:
+.RS
+.TP 15
+.B --proto -ftps
+uses the default protocols, but disables ftps
+.TP
+.B --proto -all,https,+http
+only enables http and https
+.TP
+.B --proto =http,https
+also only enables http and https
+.RE
+
+Unknown protocols produce a warning. This allows scripts to safely rely on
+being able to disable potentially dangerous protocols, without relying upon
+support for that protocol being built into curl to avoid an error.
+
+This option can be used multiple times, in which case the effect is the same
+as concatenating the protocols into one instance of the option.
