Only packages that are installable through apt-get will be shown. \n\nThis tool currently does NOT support uninstalling packages.  You may uninstall them with apt-get yourself, of course.\n\nIf you use an apt repository that allows multiple versions to be installed at once, the default version which is invoked via the php command can usually be updated via the update-alternatives system.  See the manual page update-alternatives(1) for more.\n\nThis tool always welcomes patches."  17 72
