[SyncEvolution] Usage of syncevolution 1.1.1

Hi all, I wanna use sqlite as backend for data synchronisation instead of syncevolution DB . How can I do that ? where should i modify in code or in file configuration ? also How can i get the xml messages exchanged between the syncevolution client and the server ( Funambol server for example ) ? I mean explicit xml messages not the logs detailed syncevolution-log.html ? Regards.
