"or something" - what about the zsh then?

Does the zsh look explicitly into the directory "C:\WINDOWS" then?
If not then how does it determine this value?
What if I have installed both Windows95 and WindowsNT on my disk?
Which directory gets checked first then?
(This is not just a theoretical issue!)

Well, is the order of these checks correct or isn't it? YES or NO?

I remember that some incosistencies with the
manual had been discovered recently on this list.
So - what is the complete/correct set of rules here?

Now, this is a contradiction in itself.
Does the zsh set HOME now or doesn't it?

This statement in unclear. Does the zsh set HOME,
and if so, does it change its value to a list of dirs in turn,
stopping at the first dir where it can find a zshrc?

On the contrary! The OS determines the kind of setup I have to use.
And its syntax determines how I can access the value of variables.
And from the non-description it is still not clear to me where I would have to
set the variables HOMEDRIVE and HOMEPATH - therefore I do not know whether I
should set them with the autoexec.bat and whether I would have to use the
syntax of command.com; I hope this makes the problem more clear now.
I suppose that these variables are not set within the zshrc as
they are supposed to determine the location of the setup file.

The README is very concise and not at all precise,
the changelog was pretty useless (as I remember),
and emailing you is what I keep doing as I hope
that this will be faster than reading the source. ;-)

Well, this is your chance to have your info compiled by me.
But I wonder whether it wouldn't be easier to write it up
yourself in pseudo source style, eg like this:
then test $HOME/.zshrc
then test $ZDOTDIR/.zshrc
else test $USERPROFILE\.zshrc
I just need something like this.
