I'll eat crow if wrong, but I'm guessing I know more about GNU make than
you do. It is none of the four things you claim. Also, people who say
"on the tin" need a good ass-kicking.
Is the presentation bird alive or dead? What is "fired" in this
context? Is the presentation bird unrested? What does "rested" mean in
this context? Why does the kitchen need to "butcher" the chicken that's
"rested"? Doesn't that mean the rested chicken is still alive? What
does "slowing" the other, presumably presentation, chicken mean?
