Yum is to install new programs and check for updates to existing programs installed by yum. Also not all programs are part of the core Yum repository. You can also use Dag which may contain other programs that you can install. To add Dag to yum, do the following:
Type the following:cd /etc/yum.repos.d
Add the text in the quote below to dag.repo and save the file by typeing :wq
and pressing enter.
name=Dag RPM Repository for Red Hat Enterprise Linux baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
Now you need to install the dag key by typeing the following and pressing enter:rpm --import http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt
Now when you use Yum it will also check the Dag repository.
