   a dash with the suffix of `.mp3`. The actual name of the track is arbitrary.

  +A very convenient way to create this structure is to rip CDs with https://code.google.com/p/abcde[abcde] (on 
  +your main computer and not on the Pi, of course). 
  +It will also handle multi CD books when used with commandline option `-W`, followed by
   the number of the CD:
   
   ----
  -$ abcde -W1
  -$ abcde -W2
  -----
  +$ abcde -W1 -c abcde_book.conf
  +$ abcde -W2 -c abcde_book.conf
  +...
  +----
  +
  +The configuration file `abcde_book.conf` is included in the main directory of this
  +project. Copy it to the computer you are using for ripping and use it accordingly.
  +
  +The most important configuration parameter inside this file is `OUTPUTFORMAT`:
  +
  +----
  +OUTPUTFORMAT='${ARTISTFILE}/${ALBUMFILE}/${TRACKNUM}-${TRACKFILE}'
  +----
  +
  +This will produce track names in the correct format.
   
   == Shortcomings and Improvements
   
  -* Parts of the code might not really be thread-safe, should be reviewed.
  +* Checking of changes to the currently selected book in the main
  +loop by polling is not really a good implementation.
   * The way button presses are handled could be improved. Implementation
     of an event queue might be a way to ensure that no button events are lost.
  +* Parts of the code might not really be thread-safe, should be reviewed.
  +* The language configuration for the text-to-speech engine is hardcoded.
  +This does not work if the author's name is in a foreign language
  +or a title contains foreign language words.
