Rediscovering my jailbroken #Kindle lately with #koreader and I'm kinda surprised how the #epub format feels somewhat forgotten across the web. I want to read through documentation for some stuff, and it's all perfectly laid out in a tree of pages yet it's not trivial to convert that to a sane epub.

Some documentation offers #PDF versions, but more often than not PDF conversion to epub is even less useful.

Anyone have tools they use to convert these sorts of web documents to nice epubs?
