+MacBALSA was written by Marc H. Brown <mhb@ariba.com> as part of his
+thesis work at Brown. This software is capable of performing very
+sophisticated algorithm animations. The following article contains a
+good description of the software.
+
+ Marc H. Brown, "Exploring Algorithms Using Balsa-II", IEEE
+ Computer, May 1988, 14-36.
+
+The enclosed balsa-manual.pdf gives a less technical description of
+the software. Please note that it contains Marc Brown's old address.
+His current address is <mhb@ariba.com>. It also contains some
+warnings against copying the software. Marc has assured me that it is
+OK to copy the software. I hope to replace this manual with an
+updated version that corrects these errors.
+
+It seems that MacBALSA was meant to accompany Sedgewick's Algorithms
+book.

+ Robert Sedgewick, "Algorithms", Addison-Wesley, second edition,
+ 1988, ISBN 0-201-06673-4.
+
+(There are variants called Algorithms in C, Algorithms in C++, and
+Algorithms in Modula-3.) The algorithms are organized by chapter
+number in this book. It also appears that MacBALSA was the source for
+many of the figures in the text.
+
+This is version 1.0 of MacBALSA. I produced this version using
+version Aleph 4 of the source code. It will run on a 68K or Power
+Macintosh that has the Thread Manager installed. Most Macintoshes
+produced within the past few years come with the Thread Manager
+installed.
+
+Newer releases of the MacOS had rendered version Aleph 4 of MacBALSA
+fairly unstable. In this version I have corrected all of the
+stability problems that I could identify. I have fixed a number of
+bugs. I also changed the software so that it uses threads when
+running algorithms. Please let me know if you discover any problems.
