1. install lha (i.e. brew install lha)
2. set execute permission to all scripts chmod +x {script}
3. move scripts to /usr/local/bin/
4. change directory to WHDLoad game images. (note: the script does not traverse through the subdirectorires)
5. if you have zip and corresponding lha archives for the same games, execute finished2folders.sh
6. execute zip2lha-all.sh to convert all zip archives of the current folder to lha
7. execute finished2folders.sh to move all corresponding zip and lha archives to subfolders.
