The author of this software (Philip Guo) has written a book called &quot;The Ph.D. Grind&quot; (available at <a href="http:&#x2F;&#x2F;www.pgbovine.net&#x2F;PhD-memoir.htm" rel="nofollow">http:&#x2F;&#x2F;www.pgbovine.net&#x2F;PhD-memoir.htm</a>) where, in one of the chapters, he describes how he ended up making this piece of software as part of his Ph.D.<p>The book is a nice read.
