about ()

pgwall is a small bash script, written by Thijs Kleintjens.
The purpose of writing this script was not to create something usefull,
it was to become more familiar with the Bourne Again Shell.

This script is based upon a nice little piece of software called pacgraph,
created by keenerd, available in the Arch User Repository.
Information about pacgraph is available here: kmkeen.com/pacgraph

You can copy, modify, redistribute, or anything else you want to do with pgwall, without asking me.
