Latex is excellent for typesetting and PDF.

But in this case I'd rather go for one of the "Lightweight markup formats" supported by Pandoc -> https://pandoc.org/

See also https://pod-pandoc.readthedocs.io/en/latest/Pod-Pandoc.html

But still anything involving pod2html is for me the way of minimum loss to go for, because the POD in question was designed to create HTML in the first place. And ePUB is mostly HTML

And there is even a cpan project for this App::Pod2Epub

pod2latex foo.pod && pandoc -f latex -t epub -o foo.epub foo.tex

No need to touch the LaTeX code.

«The Crux of the Biscuit is the Apostrophe»

Using LaTeX to generate HTML & ePUB from POD is quite a costly detour.

It's like putting a cake into a freight container and shipping it via Hong Kong, instead of ringing the bell at your neighbors door.

It's not only in magnitudes slower and resource hungry, it's also more prone to cause problems in the long run.
