+Two query parameters are accepted: include_versions and
+exclude_versions, both of which can take multiple values by
+specifiying them multiple times. They are passed directly to the
+B<naodash_user> function, see the documentation of L<NetHack::NAOdash>
+for an explanation of their function.

 The constructor takes a single named parameter, I<json>, that is false
 by default. The result will be returned as HTML is I<json> is false,
 as JSON if I<json> is true.
