% HISTORY
2013/04/28 v0.1  - first version
2013/04/29 v0.1a - added error handling and messages
2013/04/30 v0.2  - it's stupid to set colors explicitly -- better define TikZ
                   styles for this
2013/05/01 v0.3  - added \scales command
2013/05/01 v0.3a - set all lengths as multiples of the base unit
2013/08/25 v0.4  - added scale option that allows variable number of frets
2014/07/16 v0.5  - add `inner sep=0pt' to `root' and `show root' styles
2014/09/15 v0.6  - new options `chord-frets', `scales-frets' and `fret-number'
2016/08/16 v0.7  - new option `strings=&lt;num&gt;' makes the string number
                   adaptable which allows creation of ukulele and bass guitar
                   diagrams
                 - new option `name-below'
                 - new option `rotate=&lt;angle&gt;'
                 - new option `name-distance'
                 - new command \newfingering{name}{fingers}{roots}
