Just for fun, here's a script that reads // or # notes in a PZ3  while loading it, and shows you the notes.

If you want to make an alternate version for CR2, 

replace all 'PZ3' by 'CR2', 

delete the line

poser.CloseDocument() 

and replace

poser.LoadDocument(fn)

by

scene.LoadLibraryFigure(fn)

Same way for PP2, except use 
scene.LoadLibraryProp(fn)
