+This is experimental and it will probably not work for you but...
+
+ALSO: Please do not use any of this to steal. Theft is wrong.
+ This is meant to allow conversion of Topaz books for other book readers you own
+
+Here are the steps:
+
+1. Unzip the topazscripts.zip file to get the full set of python scripts.
+The files you should have after unzipping are:
+
+cmbtc_dump.py - (author: cmbtc) unencrypts and dumps sections into separate files
+decode_meta.py - converts metadata0000.dat to human readable text (for the most part)
+convert2xml.py - converts page*.dat, other*.dat, and glyphs*.dat files to pseudo xml descriptions
+flatxml2html.py - converts a "flattened" xml description to html using the ocrtext
+stylexml2css.py - converts stylesheet "flattened" xml into css (as best it can)
+genxml.py - main program to convert everything to xml
+genhtml.py - main program to generate "book.html"
+gensvg.py - (author: clarknova) main program to create an svg grpahic of each page
+
+Please note, gensvg.py, genhtml.py, and genxml.py import and use
+decode_meta.py, convert2xml.py, flatxml2html.py, and stylexml2css.py
+so please keep all of these python scripts together in the same place.
+
+
+
+2. Remove the DRM from the Topaz book and build a directory
+of its contents as files
+
+All Thanks go to CMBTC who broke the DRM for Topaz - without it nothing else
+would be possible
+
+ cmbtc_dump.py -d -o TARGETDIR [-p pid] YOURTOPAZBOOKNAMEHERE
+
+This should create a directory called "TARGETDIR" in your current directory.
+It should have the following files in it:
+
+metadata0000.dat - metadata info
+other0000.dat - information used to create a style sheet
+dict0000.dat - dictionary of words used to build page descriptions
+page - directory filled with page*.dat files
+glyphs - directory filled with glyphs*.dat files
+
+
+
+3. Convert the files in "TARGETDIR" to their xml descriptions
+which can be found in TARGETDIR/xml/ upon completion.
+
+ genxml.py TARGETDIR
+
+
+
+4. Create book.html which can be found in "TARGETDIR" after
+completion. This html conversion can not fully capture
+all of the layouts actually used in the book and needs to
+be edited to include special font handling such as bold
+or italics that can not be determined from the ocrText
+information or the style information. If you want to
+see things exactly as they were, see step 5 below.
+
+ genhtml.py TARGETDIR
+
+
+
+5. Create an svg description of each page which can
+be found in TARGETDIR/svg/ upon completion.
+
+All thanks go to CLARKNOVA for this program. This program is
+needed to actually see the true image of each page so that hand
+editing of the html created by step 4 can be done.
+
+Or use the resulting svg files to read each page of the book
+exactly as it has been laid out originally.
+
+ gensvg.py TARGETDIR
