Yes, I saw, thanks!

I just posted that I thought this, so thanks for the verification.
I think that'll be sufficient for me to start moving on some work.

Ok good. But then the problem is that it was stated (and seems
from my looking at the file) that the file is only Windows specific.
So why would a windows specific file look for a windows specfic
platform? Does it want to do something specific on Windows NT
that it won't do non-NT versions of Windows? I'm clearly confused
on a number of points, so go easy on me if this is too obvious :)

I'm still confused over como-tools.html, so I'll ask my question
statement as a question :} :
What is
the difference between COMO_PATH, COMO_BIN_PATH, COMO_BIN_DIRECTORY,
COMO_BASE_SETUP, and COMO_PATH_SETUP and how do they [need to] interact
and/or how are they [necessary to be] different from just
PATH and COMO_PATH? :) Seriously. I see for instance that
borland-tools.html only discusses BCCROOT. Why doesn't como
need just COMOROOT then? And/or why isn't there just a ROOT
or COMPILER_ROOT for all compilers? Or why isn't it just
assumed to be in PATH?

I probably should have said "extra". Extra in the sense that
Comeau C++ normally doesn't use them, so what does use then,
where does it use them, and why?
