If you add a .CMD file as the first entry in a .ZIP, with compression set to "none", you can rename and run the .ZIP as a .CMD, because the PK header will be treated as a nonexistent command and execution will continue after that. With a little imagination and some PowerShell I've made that into a self-extracting archive. It's a dirty hack, but I've had it working in production for years now. I want to see if I can make the batch file chimeric so it can run in a linux shell as well. Maybe that'll to be my lazy Sunday afternoon?
