Wajig is an interface to many Debian administrative tasks. The name has no particular meaning (sorry!). Written in Python, it uses traditional Debian administration and user tools including apt-get, dpkg, apt-cache, wget, and others. It is intended to unify and simplify common administrative tasks.
Wajig has evolved over many years and there's a small band of users. It has some of the same aims as the feta package and I thought to wrap the extra wajig features into feta, but a number of users suggested that wajig should stay. So it was rewritten recently from being a shell script to a python program. It is available under the GPL.
As wajig is simply my frontend to various other commands the goal of this section is more than simply demonstrating how to manage your system with wajig. Wajig may not be the answer you are looking for and that is fine. So, where ever I illustrate a procedure with wajig I will also indicate the underlying commands that are being used to effect the wajig command. You can then use these underlying commands directly if you prefer.
