/*
* This file is aimed to provide an example on how to code a Station in NML.

* The NewGRF implements a conversion of CHIPS Cow pens.
*
* Apart from this file, you will also need the following
* - Graphics, found in cows_cargo.png (in the same folder)
* - Language files, to be placed in the 'lang' folder.
* Currently english.lng is supplied.
