I can see a button in the i-installer UI which says, quite plainly,
`Change install location'.  The author has informed me that the job is
do-able, and that this mailing list is the place to ask for help on how
to do it.

(he also tells me that one shouldn't want to install teTeX anywhere but
the standard place - but I do, and I have good reasons for doing so)

I don't have such a directory (or file for that matter).  Could you tell
me what uses it and why I might want it?  Of course I can create the
directory/file pair easily, but I like to understand what I'm doing
first and I'd rather put things like that in tidy places like ~/Library
if at all possible.

I don't understand what this means.  How can there be an owner of
software that's not installed?

(I take it you mean the user who is the owner of all the files that make
up the teTeX installation.  But what if they're not all owned by the
same user?  Hmmm...)

What is the folder you refer to for?

I'm afraid I don't follow you at all here.  I know how to create folders
and I can see how to create Unix symbolic links from what you write.  I
don't see what you're trying to get me to achieve by following these
instructions.

It's not network traffic I intend to save, but human time; and I
intended to save human time by wasting network traffic.  Thrash the
computer to spare the user.

What makes you think that?

Yes, but you see, I'm an intelligent computer user and spotted this
problem.  I then found out what to do about it in order to actually
download the data I want.  I do not have `thin' versions of much - I
have fat versions.

Admittedly, I haven't actually grabbed the teTeX installer itself yet
but I've got pretty much everything else as a `fat' installer thingy.  

teTeX itself is a bit big to grab using a modem (okay, I'm on ISDN but
it's not a lot faster), and I'm not sure yet how to download it onto a
Windoze box for use on my Mac at home (I have access to a Win XP box
with a SuperJANET connection).

All very awkward...

Well, no, because I did that ages ago.

Could you explain what i-installer has to do with this?  I thought all
that sort of stuff was done by configuring the packages directly.  I
certainly don't want to get i-installer involved when I am creating new
new formats!

(and I don't use Babel - I've rolled my own on the hyphenation side
because I only want UK English and US English hyphenation patterns
available - I have a hyphen.cfg file looking like this:

Erm?  Why assume that I have a PostScript printer?  I was using HP
inkjets exclusively up until not long ago when I did, finally, buy a PS
printer.  But I've been using home computers for 25 years now and only
got round to acquiring a PS printer in the last handful of months.

Okay - thanks.

I know!  I have three internal HDDs.  Two are single partitions, one is
partitioned into two.

Can anyone help me?
