+// gif to sprite sheet Script (work in progress)
+//
+// I had some sprites that needed converting. I have a folder filled with
+// gif files. Each gif file is a tiny sprite. They are named 01..99+.gif
+// I wanted to load each of these gifs and make a sprite sheet of them and then
+// save this sheet as a image file.
+//
+// I was working on doing this but discovered the export function of the
+// tool I used had a bug where only the first sprite of a set was saved as
+// a gif. I decided not to continue at this point.
+
+// What I have here is a loader that creates x amount of textures. Then
+// the loadtexture command loads the first 10 of these gifs into
+// this array. It shows how to create a load function which can load
+// procedural generated filenames.
