# This script creates symbolic links of english images on the arabic images folder
# Just make sure the specific language image in english have the same name in arabic
# any other image in english will be symblinked on the arabic folder to avoid duplication
# When it comes to generate a sprite using Compass,
# There is a limitation of using a single asset type load path at a time
# which means, using Compass you cannot generate a single sprite from two different paths unless
# your folders are nested then it's one path using two folders.
