+# OUTPUT
+If not told otherwise, curl writes the received data to stdout. It can be
+instructed to instead save that data into a local file, using the --output or
+--remote-name options. If curl is given multiple URLs to transfer on the
+command line, it similarly needs multiple options for where to save them.
+
+curl does not parse or otherwise "understand" the content it gets or writes as
+output. It does no encoding or decoding, unless explicitly asked to with
+dedicated command line options.
