OK, here's our problem.  We have a software package installed at some 
customers sites.  We send them new releases every now and then.  During the 
setup for the new release we need to do:

if (this is an upgrade)
	Do some stuff
elseif (this is a new install)
	Do some other stuff
endif

How can I do this with RPM.  $1 is always 1, because the package name is the 
same when we do a new relase, the versions just change.  How can I do this?  
Can we tell if RPM was called with -I or -U, or is there a better way?

Mike.
