aptitude-gtk 0.6.3-3.2ubuntu1 (i386 binary) in ubuntu natty

 aptitude is a package manager with a number of useful features,
 including: a mutt-like syntax for matching packages in a flexible
 manner, dselect-like persistence of user actions, the ability to
 retrieve and display the Debian changelog of most packages, and a
 command-line mode similar to that of apt-get.
 .
 aptitude is also Y2K-compliant, non-fattening, naturally cleansing,
 and housebroken.
 .
 This package contains an EXPERIMENTAL version of aptitude that
 includes a GTK+-based graphical interface. It is INCOMPLETE and may
 not work properly. If you do not need a GUI or prefer a more stable
 interface, you can instead use the version of aptitude found in the
 package "aptitude".
