Wiring up the DS18B20 is simple.  I found pin configurations on page one of the datasheet and a wiring example on page six of the datasheet:

DS18B20 TO-92 pin configuration     DS18B20 wiring

I tied the 1-Wire BUS line I/O line 9 on the Arduino.  The rest is programming now.

Reading ‘http://www.arduino.cc/playground/Learning/OneWire’ revealed that Jim Studt created a nice OneWire library for the Arduino that, thankfully, makes this whole thing a lot easier than I thought it would be.  It seems there are a few modifications by other authors that have been useful as well.

Zimbra NE allows me to restore the user’s account to another account just fine but then what do I do to get the mail folder over to the production account. I ended up spending the weekend coding an automated restore. Right now it is very “alpha” but I thought I had better share my code with people out there who are hurting like I was.
