Charles, that’s precisely right.
I had to go dark after the initial pass in order to do the software in stealth mode. But those conversations we had developed directly into this new stuff, including the htrack format.
BTW, I did many revs to get it right, including testing it out by marking up existing pages and writing pseudocode to parse my working drafts. But a weird thing about it is that it’s a lot like M3U in the end — it’s as tight and simple as possible, but you can’t extend it by putting more elements inside a master container element.
