How to add and remove a software package with Yum.
Yum makes things easier for the user as it calculates and offers to install dependant and updated packages for you. I am running CentOS 5.3 on my machine used in the example, but this example is a very basic use of yum which includes the whole Yellow Dog, Fedora, CentOS, RedHat EL
Here is an example of installing a software package, the one I am installing is the Bean Scripting Framework package. I chose this package to demonstrate the usefulness of letting a package manager do most of the work for you.
