8 # ABC standard v1.6: http://www.gre.ac.uk/~c.walshaw/abc2mtex/abc.txt
10 # Enhancements (Roy R. Rankin)
12 # Header section moved to top of lilypond file
13 # handle treble, treble-8, alto, and bass clef
14 # Handle voices (V: headers) with clef and part names, multiple voices
15 # Handle w: lyrics with multiple verses
16 # Handle key mode names for minor, major, phrygian, ionian, locrian, aeolian,
17 # mixolydian, lydian, dorian
18 # Handle part names from V: header
19 # Tuplets handling fixed up
20 # Lines starting with |: not discarded as header lines
21 # Multiple T: and C: header entries handled
22 # Accidental maintained until next bar check
23 # Silent rests supported
24 # articulations fermata, upbow, downbow, ltoe, accent, tenuto supported
25 # Chord strings([-^]"string") can contain a '#'
26 # Header fields enclosed by [] in notes string processed
27 # W: words output after tune as abc2ps does it (they failed before)
29 # Enhancements (Laura Conrad)
31 # Barring now preserved between ABC and lilypond
32 # the default placement for text in abc is above the staff.
34 # \breve and \longa supported.
35 # M:none doesn't crash lily.
36 # lilypond '--' supported.
38 # Enhancements (Guy Gascoigne-Piggford)
40 # Add support for maintaining ABC's notion of beaming, this is selectable
41 # from the command line with a -b or --beam option.
42 # Fixd a problem where on cygwin empty lines weren't being correctly identifed
43 # and so were complaining, but still generating the correct output.
47 # Multiple tunes in single file not supported
48 # Blank T: header lines should write score and open a new score
49 # Not all header fields supported
50 # ABC line breaks are ignored
51 # Block comments generate error and are ignored
52 # Postscript commands are ignored
53 # lyrics not resynchronized by line breaks (lyrics must fully match notes)
54 # %%LY slyrics can't be directly before a w: line.
62 # * GNU style messages: warning:FILE:LINE:
65 # Convert to new chord styles.
