Scott, AB2G, passed on this gem to me:
 
http://chirp.danplanet.com/
 
It's a free programming package for many radios - Icom, Kenwood, Yaesu and more.  Just bring your own cable.
 
It can also import from csv, RepeaterBook or rfinder.
 
I discovered that (like many packages) you need to read your radio before you can edit the memories.
