Dan: "Hey, wouldn't it be great to have the docs in a nice, open standard format that works on all kinds of ereaders?"
World: "Oh, sure, you mean HTML or PDF. Yeah, we've got those already."
Dan: "Well, no - I mean all of the content in one file, not a whole bunch of files like HTML. And yes, I know, PDF is one file and has a table of contents, but it doesn't resize very nicely or reformat itself to fit a phone or tablet or 47" 1080p display. I mean epub!"
And so, after commit ed287098f29915ba416c0afc0be3ea64aa49c809, it was possible to run the following command:
a2x --format epub root.txt
and generate an Evergreen 2.2 docs (epub). HUZZAH!
