Revision 4e5d304eb7cd5589b924ffb8b423b6f15511b35d authored by Ron Burkey on 20 October 2018, 17:47:00 UTC, committed by Ron Burkey on 20 October 2018, 17:47:00 UTC
the recently-added documents about YUL, was transcribed. Because the original program contained a deliberate error in YUL (as well as some constructs that have unintentionally become errors in yaYUL), I've provided it in two forms: TRIVIUM (which matches the original scan, to the extent feasible) and TRIVIUM-repaired (which has the deliberate and unintentional errors fixed, but otherwise retains the identical functionality of the original).
