""" mup2mma extracts chords from a MUP music notation file and
creates a MMA file. For this to work the MUP file must use
the macro "C" for chord. In my MUP files I have the following:
define C bold (11) chord above all: @
This script just checks all input lines and assumes that anything
starting with "C" is a chord line.
Additional "features":
Lines in the form "// TEMPO: xx" generate a Tempo entry
"time =" lines are parsed for common time signatures
repeats are inserted as comment lines
0.3 - added options:
-m add melody lines
-l add lyrics
-o overwrite
0.4 - reformatted output
0.5 - corrected melody/lyric notation.
1.0 - converted to python 2 or 3 (March/2014)
