Creating a self updater

Care to share your code?

It's a working prototype, untidy, and very specific to my use case - so not much use to others. If more people are interested, I might refactor into a class and share it.

But the main purpose of my previous post is ZipArchive is a simple way to extract the files for installation. Have a self updater is also great when you want to quickly test some code changes on a different test environment.
