+
+This script generates split-audiobook files for each track using a copy-pasted version
+of the Audible tracklist from the Audible web player
+
+The file format is:
+
+CHAPTER1
+01:25:50
+Chapter 2 title goes here
+00:01:12
+Chapter 3 title goes here
+01:25:54
+End Credits
+00:00:59
+
+This is exactly what you'll get if you copy-paste the listing from the web player.
+
+Unfortunately, I've found that for very long Audiobooks, this isn't precise enough and the errors add up.
