Size of each installed RPM (Red Hat)

I'm working on making the Red Hat distros smaller, and I ran across this utility:

http://www.fourmilab.ch/webtools/rpmsize/

The "rpmhogs.pl" perl script will query all the RPMs you have installed, and sort them by size and display the output.

You can then target individual RPMs to remove :-)

Very useful..
