;--
;-- Usage instructions:
;--
;-- 1. Create a world info folder with name containing the string
;--    "<||ls||>" (without the double quotes).  The name can be anything as
;--    long as it contains that inside it somewhere -- for example, you could
;--    set the name to "Locations <||ls||>".
;--
;-- 2. Create a non-selective, constant world info key _in that folder_ with key
;--    "<||lslocation||>" (without the double quotes).  Every once in a while,
;--    this script will generate 20 tokens using "The current location"
;--    as the submission and save the output into the <||lslocation||> entry.
;--
;-- 3. Put some other world info entries into the world info folder.  These
;--    entries will _only_ be triggered by the contents of the <||lslocation||>
;--    entry and not by your story itself, or if it has constant key turned on.
;--
;-- You can edit some of the configuration values below to modify some of this
;-- behaviour:
;--
