Adding freshrpms to yum

yum is one of the package management systems included with FC3. Adding sources to yum other than from RedHat involves editing the /etc/yum.conf or adding a file to /etc/yum.repos.d, and adding GPG keys in the proper place.

FreshRPMs makes it easy. Just download the freshrpms-release RPM file and install it.

Later:

When that didn't work, I searched and found that you must then run

sudo yum -y check-update

to get things started properly. Anyway, that works.
