Bowerbird,
I think that many of us would like to see a practical example of what your tools can do to a PG book.
Could you please, using your tools, produce an HTML version of:
http://www.gutenberg.org/dirs/etext01/wrnpc12.txt
That's the plain text PG version of "War and Peace", and contains lots of interesting "structural elements" such as footnotes. I'd like to what your tools make of it, if you'd be so kind.
Thank you,
