This mod serves as an example of using AntiqueAtlas API. For a complete description of the API see https://github.com/Hunternif/AntiqueAtlas/wiki/API and JavaDocs.
What this mod does, is every time the player right-clicks on a block, a "test" tile is put in the Atlas. The AntiqueAtlas mod itself is a "soft" dependency (as configured in mcmod.info), meaning that this example mod will not crash if the API is not present.
