I began to read it in the info pages form and reached page 33 before learning 
from the previous thread it could be rendered as PDF. The intro is almost 300 
pages in full. I had expected 60 pages.

Stopping at page 45 in the PDF (page 61 of 271 in the PDF viewer) and looking 
back, the word `simple’ was added in 2013 and has not been applied consistently.

For others who may want to follow along, I used (vc-annotate) or `C-x v g’ 
inside:

  emacs/doc/lispintro/emacs-lisp-intro.texi

to locate details in the example section above.

Details about Emac’s version control interface are in chapter 25 of the 
emacs.pdf created by `make docs’ or in the info pages for Emacs 26.1 rc-1 in 
`28 Maintaining Large Programs’.

For now, I’ll read it carefully and keep an eye out for errorneous statements. 
Hopefully others will join and a collective 15-minutes everyday from 
contributors around the world will improve the manual.
