Dan,
I've lost track of where the latest version of your document on
publishing an ePUB from odt was located. I have two versions of this
document on my computer, but neither has a date on it, so I don't know
which is the latest or whether there is an even more recent iteration.
One has some info about both Calibre and Sigil in it; the other is
Sigil only but appears to have more detail. Please advise.
