#it works... theoretically http://i.imgur.com/2FnWB3R.jpg

#DIRECTIONS:
#
#1. Create tile sheet (make sure dimensions and layout are in line with the settings in this script)
#2. (Optional) export it somewhere (within the documents folder recommended) with a discriptive name.
#3. Open tile sheet in GIMP from what you exported. Alternatively, if you skipped 2, just make sure your layer has a desired/descriptive name
#4. Make sure the desired tile sheet is the only image open in GIMP
#5. Copy this script in entirety, in GIMP go to filters>python-fu>console
#6. Hit ctrl+v
#7. Contemplate your existence
#8. Read the green stuff outputted by the python console at the bottom to find out where your files are. Hint: it says insomniac_lemon-gimp_script in it.

#it should be easy enough to edit tiles_w and tiles_h and last_tile in order to split different sized atlases
