This content pack contains one or more tile sets (and/or other resources) as originally found in Ari Feldman's SpriteLib_GPL. In addition to these originals, modified versions of the original are present. These versions have been modified to allow TGB to load them as tile maps. The original SpriteLib_GPL (in its entirety) can be downloaded here: http://www.flyingyogi.com/fun/spritelib.html
