The features are the following: * a self-written python script
always on: When you power on the raspberry, it will boot up and start the python script with the audio book in pause The features are the following:
one button usage: The button pauses and unpauses the audio book or goes back one track when you press the button longer than 4 seconds

easy audio book deployment: When you plug in a USB thumb drive with a special name/label, the Raspberry will stop playing, mount the thumb drive, deletes the old audio book, copies the new one, rebuilds the playlist and – after unplugging the thumb drive – starts the new audiobook in pause mode * remembers position: It will always remember the last played position
multi format: Since it uses mpd, the player supports Ogg Vorbis, FLAC, OggFLAC, MP2, MP3, MP4/AAC, MOD, Musepack and wave * only one audiobook: There will always be only one audio book on the Raspberry
