explination if you were a Windows user..
apt is kinda like a manual Windows Update. I said kinda like.. no flames..
when you type apt-get install packagenamehere it downloads the program from the web and installs it on your Linux box. Very Nice.. You dont have to do anything else.
To get apt installed on your linux box just download the rpm for the ver of RH (orinally a debian thing, also available for RH, Fedora, YellowDog and more) you have.
Go to the directory where you downloaded it and type:
rpm -Uvh packagenamehere
rpm is the RedHat Package Manager
-Uvh is Upgrade show verbose and show hashes
(if there is nothing to upgrade it defaults to install)
packagenamehere = the name of the file you downloaded
once it is installed you will want to type:
apt-get update == this updates the package list
then type
apt-get install packagename (where packagename is the name you find on frshrpms.net)
hope this helps you some
ps. im sure you know this but all must be done as root
