The purpose of this software is to create a method for you to download and store your books just in case Audible fails for some reason. +I recently converted this script to bash instead of perl. Something about more people knowing bash or something rather. +Additionally I put some work into creating chaptered files as well as the mp3 version.

This will be used by ffmpeg to perform the initial audio convert.
