The Jig is a form of lively folk dance in compound meter, as well as the accompanying dance tune. It developed in 16th-century England, and was quickly adopted on the Continent where it eventually became the final movement of the mature Baroque dance suite (the French gigue; Italian and Spanish giga). Today it is most associated with Irish dance music, Scottish country dance and the Métis people in Canada. Jigs were originally in duple compound meter, (e.g., 12/8 time), but have been adapted to a variety of time signatures, by which they are often classified into groups, including light jigs, slip jigs, single jigs, double jigs, and treble jigs.

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.
