My bad, I thought the `help' target was a GNU standard.

`make help' would display a one-line help about the various
available targets:

# make all	
# make install	
# make TAGS	
# make clean  (or  make mostlyclean)
# make distclean
# make maintainer-clean
# make extraclean
# make bootstrap

(Taken from INSTALL, not from the actual Makefile.)

If I'm not confused, the last two targets are not in the 
GNU standards (`bootstrap' and `extraclean').  

Documenting `make extraclean' is not important IMO but 
documenting `make bootstrap' could be: there are often
questions on emacs-devel which are answered by "You need 
to `make bootstrap'."

I guess `make help' could give a better exposure to this
option?
