+
+Prerequisites:
+
+   - Kindle for Mac.app Version 1.0.0 Beta 1 (27214)
+     (this is the original version)
+
+	or
+
+     Kindle.app Version 1.2.0 (30689)
+     (this is the current version at Amazon)
+
+
+   - XCode Developer Tools **must** be Installed 
+    (see your latest Mac OS X Install Disk for the installer)
+
+
+The directions for use are:
+
+1. double-click on K4Munswindle.pyw
+
+In the window that opens:
+
+– hit the first '...' button to locate your Kindle Application 
+     if it is not in /Applications
+
+– hit the second '...' button to select an output directory 
+      (defaults to your Desktop)
+
+– hit the 'Start' button
+
+After a short delay, your Kindle application should open up automagically
+
+2. In Kindle for Mac:
+
+ - hit the  “Home” button to go home. 
+
+ - double-click on ONE of your books.
+   This should open the book.
+
+3. Once the book you want is open
+
+-  hit the “Home” button and then exit the Kindle for Mac application
+
+4. Once you have exited the Kindle for Mac application you should see one of the following:
+
+  - If the book you selected was a Topaz Book:
+
+      A Warning message will appear in the Conversion Log indicating 
+      that the book you opened was Topaz, along with the 8 digit PID 
+      needed to convert it using Topaz_Tools
+
+  - If the book you selected was a Mobi book:
+
+      MobiDeDRM will be automagically started in the Conversion Log 
+      window and if successful you should find your decoded book in 
+      the output directory.

+# This is a python script. You need a Python interpreter to run it.
+# For example, ActiveState Python, which exists for windows.
+#
+# It can run standalone to convert files, or it can be installed as a
+# plugin for Calibre (http://calibre-ebook.com/about) so that
+# importing files with DRM 'Just Works'.
+#
+# To create a Calibre plugin, rename this file so that the filename
+# ends in '_plugin.py', put it into a ZIP file and import that Calibre
+# using its plugin configuration GUI.
+#
+# Changelog
+#  0.01 - Initial version
+#  0.02 - Huffdic compressed books were not properly decrypted
+#  0.03 - Wasn't checking MOBI header length
+#  0.04 - Wasn't sanity checking size of data record
+#  0.05 - It seems that the extra data flags take two bytes not four
+#  0.06 - And that low bit does mean something after all :-)
+#  0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
+#  0.08 - ...and also not in Mobi header version < 6
+#  0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
+#  0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
+#         import filter it works when importing unencrypted files.
+#         Also now handles encrypted files that don't need a specific PID.
+#  0.11 - use autoflushed stdout and proper return values
+#  0.12 - Fix for problems with metadata import as Calibre plugin, report errors
+#  0.13 - Formatting fixes: retabbed file, removed trailing whitespace
+#         and extra blank lines, converted CR/LF pairs at ends of each line,
+#         and other cosmetic fixes.
+#  0.14 - Working out when the extra data flags are present has been problematic
+#         Versions 7 through 9 have tried to tweak the conditions, but have been
+#         only partially successful. Closer examination of lots of sample
+#         files reveals that a confusin has arisen because trailing data entries
+#         are not encrypted, but it turns out that the multibyte entries
+#         in utf8 file are encrypted. (Although neither kind gets compressed.)
+#         This knowledge leads to a simplification of the test for the 
+#         trailing data byte flags - version 5 and higher AND header size >= 0xE4. 
+#  0.15 - Now outputs 'hearbeat', and is also quicker for long files.
+#  0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
