+Long: form-string
+Help: Specify HTTP multipart POST data
+Protocols: HTTP
+Arg: <name=string>
+See-also: form
+---
+Similar to --form except that the value string for the named parameter is used
+literally. Leading \&'@' and \&'<' characters, and the \&';type=' string in
+the value have no special meaning. Use this in preference to --form if
+there's any possibility that the string value may accidentally trigger the
+\&'@' or \&'<' features of --form.
