Description:
Nullsoft Scriptable Install System (modified for Debian)
NSIS is a tool for creating quick and user friendly installers for Microsoft Windows (Win32) operating systems. . NSIS creates installers that are capable of installing, uninstalling, setting system settings, extracting files, etc. Because it's based on script files, you can fully control every part of your installers. The script language supports variables, functions, string manipulation, just like a normal programming language - but designed for the creation of installers. Even with all these features, NSIS is still the smallest installer system available. With the default options, it has an overhead of only 34 KB.
