Exactly.  After all, if the install program itself runs, then djverify
ought to be able to run as well.  One might also want to compile the
installer with the special stubify so the djverify batch file will work
with it too.

For example:

% djverify		<-- runs just djverify
% djverify install	<-- runs the installer which runs djverify

You could even make an 'install.bat' which invokes 'djverify.bat' on
'install2.exe' which calls 'djvrfy2.exe'.  :)

You'd still need to distribute cwsdpmi with the installer, which would
effectively make it an integral part of the djgpp package, wouldn't it? 
It is distributed separately now, but there seem to have been so many
problems getting people to use it that this might not be a bad idea. 
(The only problem being keeping up with newer versions of cwsdpmi...)

BTW, I will work on making the djverify output properly formatted ASAP,
as soon as I've finished putting in all the detection functionality. 
Substance before form, right?  ;)  Mark, when you get finished with a
preliminary version of the installer, I'll hopefully be ready to send
you information on my formatting structure so we can coordinate.  I
think I'm going to be putting in some major work this weekend...
