IzPack is a powerful software installers generator for the Java[tm] platform. It uses a very modular architecture that lets you make the installers work as you want, not as the software wants it to work. It is also possible to extend it to suit your needs since it has been designed with this purpose in mind from the start.
The installers generated by IzPack are independant of the target operating system. It has been running successfully on Linux/i386, FreeBSD, Solaris, MacOS X and Win32. All it needs is a Java[tm] Runtime Environment.
