+---
+Specify the User-Agent string to send to the HTTP server. To encode blanks in
+the string, surround the string with single quote marks. This header can also
+be set with the --header or the --proxy-header options.
+
+If you give an empty argument to --user-agent (""), it will remove the header
+completely from the request. If you prefer a blank header, you can set it to a
+single space (" ").
