+#
+# Enhancements (Roy R. Rankin)
+#
+# Header section moved to top of lilypond file
+# handle treble, treble-8, alto, and bass clef
+# Handle voices (V: headers) with clef and part names, multiple voices
+# Handle w: lyrics with multiple verses
+# Handle key mode names for minor, major, phrygian, ionian, locrian, aeolian,
+# mixolydian, lydian, dorian
+# Handle part names from V: header
+# Tuplets handling fixed up
+# Lines starting with |: not discarded as header lines
+# Multiple T: and C: header entries handled
+# Accidental maintained until next bar check
+# Silent rests supported
+# articulations fermata, upbow, downbow, ltoe, accent, tenuto supported
+# Chord strings([-^]"string") can contain a '#'
+# Header fields enclosed by [] in notes string processed
+# W: words output after tune as abc2ps does it (they failed before)
+
+# Enhancements (Laura Conrad)
+#
+# Barring now preserved between ABC and lilypond
+# the default placement for text in abc is above the staff.
+# %%LY now supported.
+# \breve and \longa supported.
+# M:none doesn't crash lily.
+# lilypond '--' supported.
+
+# Enhancements (Guy Gascoigne-Piggford)
+#
+# Add support for maintaining ABC's notion of beaming, this is selectable
+# from the command line with a -b or --beam option.
+# Fixd a problem where on cygwin empty lines weren't being correctly identifed
+# and so were complaining, but still generating the correct output.
+
+# Limitations
+#
+# Multiple tunes in single file not supported
+# Blank T: header lines should write score and open a new score
+# Not all header fields supported
+# ABC line breaks are ignored
+# Block comments generate error and are ignored
+# Postscript commands are ignored
+# lyrics not resynchronized by line breaks (lyrics must fully match notes)
+# %%LY slyrics can't be directly before a w: line.
+# ???
+
+
+
+#TODO:

+# * coding style
+# * lilylib
+# * GNU style messages: warning:FILE:LINE:
+# * l10n
+#
+# Convert to new chord styles.
