From Fedora Project Wiki

This page is meant to give an overview of what needs to happen so that FE contributors can update the Extras comps.xml file.

A discussion was started by Eric R. Meyers back in July on the fedora-extras-list in this thread:
https://www.redhat.com/archives/fedora-extras-list/2005-July/msg00436.html
along with another message from Eric in August :
https://www.redhat.com/archives/fedora-extras-list/2005-August/msg01509.html

Unfortunately, the URL Eric put in his August message is now broken.
