     71Metapackages are packages which don't include any software, only control information.  This is useful for defining a set of packages that provide a certain functionality.  For example, the `debathena-standard` metapackage is designed to provide basic Athena functionality, such as Kerberos, AFS, etc.  You don't need to know the many individual packages that provide this functionality, because debathena-standard either _Depends_ or _Recommends_ those packages.  This way, if we suddenly change filesystems, or add some new functionality, we can update the debathena-standard metapackage, and let the package manager take care of making the individual changes.
