Introduction

RPM, which stands for Red Hat Package Manager, is a well-known and mature package manager used by all Red Hat flavor distributions, as well as SuSE. With RPM the packager can define relations between packages, and even with versions of packages – for example, an Apache Tomcat server needs proper Java environment present to be able to run.

On the other hand, to install a Java environment, you don’t need a Tomcat server – you may decide to run some different Java based application, maybe one written by yourself started by hand when needed to do it’s job. In other words, the Tomcat server depends on Java.
