yum – the packaging manager for my machines

yum is an automatic updater and package installer/remover for rpm systems. it automatically computes dependencies and figures out what things should occur to install packages. it makes it easier to maintain groups of machines without having to manually update each one using rpm. yum has a plugin interface for adding simple features. yum can also be used from other python programs via its module interface.
