Aptitude is a terminal-based apt frontend 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 extreme flexibility and customization.
Aptitude is also Y2K-compliant, non-fattening, naturally cleansing, and housebroken.
The documentation is in ./doc in DocBook format; to generate it:
* install docbook-xsl, xsltproc, and html2text
* run "./configure"
* run "make -C doc"
