+-- Minetest Mod: hotbar
+--      Version: 0.1.0
+--   Licence(s): see the attached license.txt file
+--       Author: aristotle, a builder on the Red Cat Creative Server
+--
+-- This mod allows the player to set his/her own hotbar slots number
+-- by adding a new command.
+--
+--   hotbar [size]
+--
+-- By itself, hotbar types the hotbar slots number in the chat;
+-- when it is followed by a number in the correct range that is [4,16],
+-- the command accordingly sets the new slots number.
+--
+-- Features:
+-- - It permanently stores the user's preference by setting and retrieving
+--   the "hotbar_slots" key in the configuration file.
+--
+-- Changelog:
+-- - The hotbar is now correctly shown even when there are no items in it.
+--
+-- FYI
+-- The potential range of the hotbar slots number is [1,16]: the next update
+-- will cover it too. :D
+--
+-- For now this is all folks: happy builds and explorations! :)
