Creating a dummy RPM

[James Colannino <james colannino qslabs com>]

Hi everyone.  I've been googling around, but haven't found a good answer 
to this problem yet.  I'm looking to create a dummy RPM whose purpose on 
the system is really nothing more than to be installed and to show up in 
RPM queries (I don't want it to actually install any files.)

How exactly should I go about this?  I've played around with creating a 
spec file, but so far I haven't gotten anything to work.  Thanks :)
