INPUT-RESOURCE-PACK does not have to be in a .zip file. If it is unzipped already then that is ok. If it is zipped, this script will unzip it into this directory.
OUTPUT-NAME is optional, if no output name is given, the resulting MineClone2 texture pack will be written to OUTPUT-NAME, or set to the value of .pack.name in the pack.mcmeta file.
OPTIONS may be one of:
-h --help Display this usage text.
-v --version Display the version of this script and then exit.
