Make sure all script files are executable. (chmod +x )

Add custom cleaning to clean.sh (You might also want to alter the chapter.py which splits files into chapters)

When done run: ./epub_cleaner.sh

The output file will be called 'clean.epub'. Rename it as you like.

NOTE: A tmp folder is used and will be deleted when running the script. The tmp folder is named 'tmp' and you will not be prompted before it is deleted.

Linux/OSX only. (should run fine in Cygwin though)
