The author would like to thank the members of the yum mailing list, especially Seth Vidal and Michael Stenner for creating yum, Russ Herrold for taking a first stab and some of its documentation and Jonathan Pickard (co-author of the nascent Yum HOWTO). The good stuff in yum is due to their hard work, the errors in this article are my own.
