This is a draft of a future yum HOWTO, offered up here for private comment by initially Seth and Michael and later by (I imagine) the yum list. If you've found this in the meantime via google, feel free to use it but beware -- it may be openly wrong or misleading in places.
Note Well: This is a Request for Comments only; Use at your own risk, and please return comments and corrections to rgb (or better, the yum mailing list) for encorporation into what I hope to be a dynamic document associated with a project, rather than a static prescription that may, in fact, be heavily flawed.
