New Linux users may be content with automatic updates and the package information shown by desktop tools, but more experienced users are generally more cautious and demanding.
Experienced users, for instance, may want to assess the risk of an upgrade by studying its dependencies before they begin, or to overcome a package conflict by using versions from an older repository. Because of Debian's long history of providing for advanced users, this sort of information is available from several different sources -- from the apt-cache command, from distribution Web sites, and, in Ubuntu, with the new Ubuntu Simple Package Crawler.
