The program will certainly do the job but like many powerful programs (r.g. Calibre) it has a lot of options and commands which have to be learnt.
The first part of the automation I want means opening the Calibre editor automatically (for a book specified in Calibre Library view), using the icon bar to run certain operations and deal with the Report screens produced, wait while I deal with errors in the epub the editor has found after which it should save the epub and exit editor and start on part 2.
I am making progress though and have got about half of part one done. The thing that is slowing me down is that I am having to learn bow to use the program at the same time.
All good fun
