   9 This file also shows how fingerings can be included in the chords
  10 used as reference points for the chord lookup, and displayed in
  11 the fret diagram and the @code{TabStaff}, but not the music.
  12
  13 These fretboards are not transposable because they contain string
  14 information.  This is planned to be corrected in the future.
