Note that the PG/submitter sausage-making chain typically runs:
Txt->html->epub->mobi
Well, here is one place where improvement can be made.
Txt-> html->epub
->mobi
This would allow for better tweaking. I one is worried about doing
parts of the conversion twice one can always put that in intermediate
files and go on from there. It is all a mater of modularity and careful design.
