25 # ABC standard v1.6: http://abcnotation.com/
27 # Enhancements (Roy R. Rankin)
29 # Header section moved to top of lilypond file
30 # handle treble, treble-8, alto, and bass clef
31 # Handle voices (V: headers) with clef and part names, multiple voices
32 # Handle w: lyrics with multiple verses
33 # Handle key mode names for minor, major, phrygian, ionian, locrian, aeolian,
34 # mixolydian, lydian, dorian
35 # Handle part names from V: header
36 # Tuplets handling fixed up
37 # Lines starting with |: not discarded as header lines
38 # Multiple T: and C: header entries handled
39 # Accidental maintained until next bar check
40 # Silent rests supported
41 # articulations fermata, upbow, downbow, ltoe, accent, tenuto supported
42 # Chord strings([-^]"string") can contain a '#'
43 # Header fields enclosed by [] in notes string processed
44 # W: words output after tune as abc2ps does it (they failed before)
46 # Enhancements (Laura Conrad)
48 # Barring now preserved between ABC and lilypond
49 # the default placement for text in abc is above the staff.
51 # \breve and \longa supported.
52 # M:none doesn't crash lily.
53 # lilypond '--' supported.
55 # Enhancements (Guy Gascoigne-Piggford)
57 # Add support for maintaining ABC's notion of beaming, this is selectable
58 # from the command line with a -b or --beam option.
59 # Fixd a problem where on cygwin empty lines weren't being correctly identifed
60 # and so were complaining, but still generating the correct output.
64 # Multiple tunes in single file not supported
65 # Blank T: header lines should write score and open a new score
66 # Not all header fields supported
67 # ABC line breaks are ignored
68 # Block comments generate error and are ignored
69 # Postscript commands are ignored
70 # lyrics not resynchronized by line breaks (lyrics must fully match notes)
71 # %%LY slyrics can't be directly before a w: line.
80 # * GNU style messages: warning:FILE:LINE:
