aptitude 0.4.11.11-1ubuntu10 (i386 binary) in ubuntu lucid

 aptitude is a terminal-based 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.
