/*
* Routines to copy information from a Gaim buddy list into an
* Evolution addressbook.
*
* I currently copy IM account names and buddy icons, provided you
* don't already have a buddy icon defined for a person.
*
* This works today (25 October 2004), but is pretty sure to break
* later on as the Gaim buddylist file format shifts.
