Scripted uninstall of Shavlik Protect Agent?

So now that we have our installation script working. What options are there for uninstalling?

If we do it manually through Add/Remove Programs, we first have to uninstall any Engines (Patch and/or Asset) and then we can remove the Agent itself.

Is there a switch for the STPlatformUpdater.exe file that will result in everything being uninstalled from the machine?

Or will I have to script msiexec /X for each item?

Thanks,
