Is apt-get purge --auto-remove packagename a valid command? Or, does it have to be apt-get remove --purge --auto-remove packagename? The Ubuntu manpage for apt-get (http://manpages.ubuntu.com/manpages/precise/man8/apt-get.8.html) only mentions using the --auto-remove option "If the command is either install or remove...", so I was wondering if it could also be used with the purge command, since that is just a shortcut for the remove command with the --purge option. Thank you.
