Within the limits of what jbig2 can do, this is a delightful tradeoff of readability for size. Great work! As a daily driver version of the manual it seems far more than adequate given that it's about the size of a baby's pinky nail. I'd love to see all the variants people are working on consolidated into a single collection once the dust settles. No doubt those who come after us would benefit from scrounging all over the internet hunting down which copy is which, or losing track of the reference scan. We already run into this problem today with slightly divergent copies of the same document becoming "welp, that's all we've got." Thanks for offering this up!
