Wajig
Wajig is a simplified wrapper to Debian's package management system dpkg/ APT. Wajig provides the functionality of apt-get, dpkg, dpkg-deb, apt-cache and other tools. These tools launch as a subprocess. Wajig also provides extra functionality beyond that of the stock apt and dpkg tools. For example, the command wajig sizes provides a listing of all installed packages and the amount of disk space they require, from smallest to largest.
