 Changelog
 ---------
+0.6.0
+* Adds several optional arguments to script json elements:
+** output_format: determines how the tilemap text file gets rendered. Possible values are "atlas", "thingy", null
+** leading_zeroes: Forces tilemap output to always be 16-bit.
+** tile_offset: Adds a constant value to the tile index.
+                Useful if you want the tilemap to start counting somewhere other than zero.
+** raw_fn: Filename for raw tile graphic png output.
+** deduped_fn: Filename for compressed tile graphic png output.
+** tilemap_fn: Filename for text index tilemap file.
+
 0.5.0
 * Introduce a master 'game.json' file in order to enable batch processing, for
   games which use multiple scripts that have different fonts or rendering
