1	-- How to try this example:
2	-- 1) Move this file into a new "afs_test" directory under mods and rename it "init.lua".
3	-- 2) Create a "depends.txt" file in the new directory with the following lines of text:
4	-- nyancat
5	-- formspecs
6	-- 3) Launch your Minetest server and enable the "afs_test" mod. Then, login as usual!
