I posted a URL to update-setup recently, possibly in cygwin-apps.

I'm not sure why you are referring to it, though.  The setup.ini that
update-setup produces is the same old setup.ini that is currently in
use.  The "rh" script works on it to produce a categorized version.

No.  I just wrote the script to provide a baseline that we could use
going forward.  I did want it to be as robust as possible so that I
could use it to regenerate things in case of a catastrophe but I don't
think that it will ever be used again after this initial go around.

That's why the script is in a "temp" directory.

See above.  I only wanted people to change the script so that I
could easily regenerate setup.ini in the next two weeks, or whenever
we release the new version of setup.exe.

I wasn't trying to open up a discussion of where the data would be
stored.  That ship has sailed.  I sent a message about this weeks
ago which had no discussion, IIRC.

Yes.  The setup.ini in CVS is the one that failed.  That is why I included
it.  I guess I'll have to debug this further.

Or, the maintainers could change the setup.ini file as I suggested.
I don't see that it makes a big difference except that I can delay
adding the parsing of extra fields in update-setup.  If you create
a setup.hint file in contrib/latest with the new fields now it is
possible that update-setup will croak.

Since I've gotten almost no response to my request that people inspect
the dependencies in setup.ini I think we'll actually sail by the
week mark very soon, anyway.

I actually expected that almost no one would respond and this is
exactly why I wrote the script.  Otherwise, I'd be sending out
"Please update your package info!"  "Really!"  "Come on!" mail
for the next four weeks and would just end up doing it myself.

This is the second or third time that I've asked for updates
and only a small percentage of package maintainers have responded.
