 Options for "listify" action:
 
+ * -append      - This appends the list to the current page that is already
+                  existing (appending to the bottom by default).
  * -overwrite   - This overwrites the current page with the list even if
                   something is already there.
  * -showimages  - This displays images rather than linking them in the list.
