# A script that generates data files for Android apk
# Below are simple configuration variables
# It's allowed to set "all" for KARTS and TRACKS if it's intended to create
# package with full data.
# The karts and tracks directories shouldn't exist in ASSETS_DIRS variable
# because they are handled separately
# The TEXTURE_SIZE and SOUND_QUALITY take effect only if DECREASE_QUALITY has
# value greater than 0
# The script needs imagemagick and ogg utils installed to use DECREASE_QUALITY
# feature
