Quick Help 

Theory of operation/use: 

Yum works by providing the headers of all the rpm packages in any system repository. These headers are stored on the webserver in a subdir of the top level of the repository. The client downloads all of the headers of the packages it doesn't have installed or of packages that have been updated. It uses the headers to determine the dependencies it will need using rpm's internal dependency calculation. Once it knows what rpms it will need it downloads them and performs the transaction.
