-- Hedgewars Shotgun Training
-- Scripting Example

-- Lines such as this one are comments - they are ignored
-- by the game, no matter what kind of text is in there.
-- It's also possible to place a comment after some real
-- instruction as you see below. In short, everything
-- following "--" is ignored.

---------------------------------------------------------------
-- At first we put all text we'd like to use in some arrays.
-- This way we're able to localize the text to be shown without
-- modifying other files.
-- The language to be used is stored in the global variable
-- 'L' that is set by the game (string).
-- Text may then be accessed using "arrayname[L]".
