That's three or more files in a zip archive. I will make the change to the code for my own use, as I do not intend to mess with several files, but keep everything in one file as opposed to an archive. I may also add .gz pipe support, if I can be bothered. And a ~/.html2lrf file which can store defaults, since it's a pain to retype them all the time.
Besides, html2lrf doesn't accept such a zip file either, last I checked, so that doesn't help, really.
That said, I want to thank you for making html2lrf. It's saved me a lot of time and is an excellent tool. If it wasn't, I wouldn't be bugging you about it.
txt2lrf however doesn't work for me. It never finishes. =(
