The --purge option to "apt-get remove" does _not_ remove pre-requisite packages. It deletes any configuration files for the package, in addition to the package contents itself. A normal "apt-get remove" without that option leaves the config files alone in case you ever want to install that package again and do not want to rewrite your carefully crafted configuration.
