*all* the stuff? Please don't do that literally.
The garrulity
quotient of info pages dwarfs even that of the most excessive
;-)
modern man pages. But I appplaud the intent to assure
man
pages are complete.
info pages clearly are redundant. Even worser under linux most
of them visualizing man pages, whereas hardly any man page is missing.
They are emacs style help pages in the tradition of twenex/its, and I tell you that a few
years ago one guy (not me) recommended in the emacs developer list to replace tekinfo by
something modern like .html.
Thus the question isn't man or tekinfo for linux documentation but html/markup or or
tekinfo for emacs build-in self documentation.
