* Constructor should collect all the data needed to perform the action
* Prepare() does any lengthy set-up action (uncompressing, patching, etc.)
* Complete() is called to complete the action
* Abort() is called when update is aborted
* You are guaranteed to be called with Complete() or Abort() before finalize
* If your Complete() throws, you'll also get called with an Abort()
