-An alternative way to provide variables. Repeat this option to provide multiple variables.
+An alternative way to provide variables one at a time. This option can be repeated to provide
+multiple variables.
If used in combination with L</"--variables JSON">, this option is silently ignored.
When unpack mode is enabled, if the response completes with no errors, only the data section of
the response is printed and the program exits 0. If the response has errors, the whole response
-structure is printed as-is and the program exits 1.
+structure is printed as-is and the program exits 1. See L</EXAMPLES> to see what this looks like in
+practice.
