+	- bf: segfault during MIDI output  with mi2mu output.
+	- kludge: parse error beyond eof
+	- don't read ini if toplevel file not found
+	- accumulate \kern in TeX output.
+	- bf: try to prevent long lines; TeX breaks on them.
+	- naming: Pointer->Link, IPointer->Pointer
+	- undocced  fix (MB)
+	- GMP manifesto.

+pl 61.jcn4
+	- mi2mu -p -s16 fugua2.midi getting better!
+	- bf: Duration_convert quantify threshold down
+	- bf: (on quantify): tcols quantified; no silly voices

+pl 61.jcn3
+	- lily parsing speedup: backup rules for lexer.l
+	- bf: mi2mu, using midi_voice list...
+
+pl 61.jcn2
+	- all in all mi2mu speedup of about factor 8 since pl61
+	 (fugue.midi 82.72user to 10.30user on a 586.133)
+	 what about lily?
+	- binary search on track-columns

+	- mi2mu parsing speedup: backup rules for midi-lexer.l
+	- bf: zero denominator
+**********
 pl 62
 	- make clean bf: remove lex & yacc files too 
 	- added kludge in case measure too long 
 	- added kludge in case of unconnected columns.
 	- kludged columns get error marker
 	- kludged lines get error marker
