This file has not been updated since I have taken over
the support of the abcMIDI package. To see the list
of the latest versions see the readme.txt file. To see
a log of all the changes I have made see the file CHANGES.
The abcguide.txt and the unix (linux) man files (eg. abc2midi.1)
contain the latest user guides. The abcguide.txt probably
contains the most detail. The official version number
of the abcMIDI package is given in the file VERSION.
Seymour Shlien 26 October 2003.

------------------------------------
1. abc2midi was found not to handle comments at end of lines properly.
This was fixed in the source code with release 1.2.1 of abc2midi.
2. midi2abc was generating %MIDI instead of %%MIDI for a program change.
This was fixed in release 1.6.1
