Dividing Daisy Audiobooks.

[Linux for blind general discussion]

Willem here.
You would first need to get rid of the encryption before any of the tools 
would be usable.
Exactly how you would go about making a daisy book with only some of the 
content of the original one, depends on if you have daisy3 or daisy 2.2 
books.
It boils down to unzipping the book and removing some entries from the 
.opf and nav.xml files and then removing the relevant files from the 
directory structure.  This is for daisy3, for daysi2.2, it is the same 
idea, but different files to be edited.
HTH, Willem
