Address Book Manipultor Help needed

[dannyo73]

I am trying to get an abandoned project using Productive Computings Address Maniputor Plug-in working, and I'm getting close without really knowing anything about scripting. I have the basic functions working, but I need to figure out how to update existing records when importing from the address book. My current options are either delete existing records before each import or end up with duplicate records. Anybody out there working with this plugin with some hints, tips, etc.
