-- Hedgewars SniperRifle 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 implement the localization library using loadfile.

-- This allows us to localize strings without needing to think

-- about translations.
