 The second form is similar, but also shows options which can be defined
 but are not currently set to any value.
 
+Both forms take an option C<--json> in which case the options are dumped
+in JSON format. In addition, with C<--json> the two forms dump the same
+data. For the format of JSON output see C<tlpkg/doc/JSON-formats.txt>,

 In the third form, if I<value> is not given, the setting for I<key> is
 displayed.  If I<value> is present, I<key> is set to I<value>.
