+
+# This is a simple tool to identify all Amazon Topaz ebooks in a specific directory.
+# There always seems to be confusion since Topaz books downloaded to K4PC/Mac can have
+# almost any extension (.azw, .azw1, .prc, tpz). While the .azw1 and .tpz extensions
+# are fairly easy to indentify, the others are not (without opening the files in an editor).
+
+# To run the tool with the GUI frontend, just double-click on the 'FindTopazFiles.pyw' file
+# and select the folder where all of the ebooks in question are located. Then click 'Search'.
+# The program will list the file names of the ebooks that are indentified as being Topaz.
+# You can then isolate those books and use the Topaz tools to decrypt and convert them.
+
+# You can also run the script from a command line... supplying the folder to search
+# as a parameter: python FindTopazEbooks.pyw "C:\My Folder" (change appropriately for
+# your particular O.S.)
+
+# ** NOTE: This program does NOT decrypt or modify Topaz files in any way. It simply identifies them.
+
+# PLEASE DO NOT PIRATE EBOOKS! 
+
+# We want all authors and publishers, and eBook stores to live
+# long and prosperous lives but at the same time  we just want to 
+# be able to read OUR books on whatever device we want and to keep 
+# readable for a long, long time
+
+#  This borrows very heavily from works by CMBDTC, IHeartCabbages, skindle, 
+#    unswindle, DarkReverser, ApprenticeAlf, DiapDealer, some_updates 
+#    and many many others
+
+# Revision history:
+#   1 - Initial release.
