# A quick and dirty image combiner for CSS sprites
# Name your files something along the lines of file_name_1.jpg (all with same extensions, 
# including casing if important on your OS) and this script will combine them in order,
# create a directory named 'sprites' and put the resulting CSS sprite image in that dir.
# Run this script in the directory that contains files that you want to combine. Takes
# one argument, specifying the highest number that the script will go up to. It defaults to 3.
# So if you have # 4 images for each sprite, simply pass the number 4 to the script like so:
# ./spriter.rb 4
