Missing info and dangling references on manual page "Preparing for TeX"

[Alan Mackenzie]

Hello, Texinfo.

I'm reading the Texinfo manual version from version 6.6 (16th February
2019).

1/- On page "Preparing for Texinfo", We have:

    TeX needs to know where to find the 'texinfo.tex' file that the
    '\input texinfo' command on the first line reads.

There is then an absence of any direction on how to give TeX this
information.  The paragraph continues with unrelated information.  This
is disconcerting.


2/- (Same page, a bit lower down):

    Optionally, you may create a file 'texinfo.cnf' for site
    configuration.

Yes, but WHERE?  This file needs to be in some directory.  Which one?
The manual page should surely state this.


3/- (A bit lower down still):

    If neither of the above locations for these system files suffice,
    you can specify the directories explicitly.

There are no "above locations" in this page that I can see.  Is this a
hangover from some reorganisation of the page which removed these "above
locations"?


4/- (Still further down):

There's a minor typo: "respeictvely" should read "respectively".


5/- When TEXINPUTS isn't set, where does texi2dvi etc. try to find
texinfo.tex?  I couldn't see this anywhere on this page.
