While peaple of MS are telling bad things about the OpenSource Concept , you’ll find [here] the first contribution of Microsoft in opensource, it’s no a so great project (Hosted at sourceForge), wix is “The Windows Installer XML (WiX) is a toolset that builds Windows installation packages from XML source code. The toolset supports a command line environment that developers may integrate into their build processes to build MSI and MSM setup packages.” under IBM CPL licence ( a derived GPL by Big Blue) the idea is really cool, and showing MS interest on Opensource movement, this startup promises a long adventure raod of the bill boys with the penguin.
