Mainly, it's a little bit of a slipstreamer, customizer, reducer and iso creator all in one package. Works for every version of Windows XP installation, so far tested up to slipsteamed SP2 build 2135. To avoid confusion, this is for pre-installation, not like XPlite which is post installation customizer.

It's written in C# (.NET) so you will need Framework to run it.
