I don't like the way Calibre downloads feeds and bundles them into EPUB files. Right now I read my RSS feeds by reading twice-a-day HTML dumps produced by rawdog. Those HTML dumps don't convert nicely to EPUB via Calibre either.
I've got quite a few feeds in the rawdog config file. There are probably tools that can be scripted together including rsstail perhaps. Taking rsstail output and transmogrifying it to epub might be simplest BUT getting from start to finish isn't sorted.
What's a way forward to start with?
