A lot less than before (360) POP was moved into CMS script file. The 
original reason was the ease of editing/dealing with the text.

a motivation was that the POP was subset of the architecture "red book"
(from it being distributed in a "red" 3-ring binder). As CMS script
file, it allowed pertinent information to be kept together (for easy
edit & management), but CMS command line option controlled whether the
POP subset was printed or the full architecture manual was printed.
