Merge Replication Custom Conflict Resolver

Hi.
Anybody knows where can I find more info about "Merge replication custom
conflict resolver"?
I have readed the "Chapter 30" of "SQL Server 2000 Resource Kit" but it's
very little. I need more details.
Thanks and greetings.
Thanks but I need a COM based conflict resolver because SP is only for
update conflicts.
|||I do not find much more than you. The 1st document are about SQL Server 2005
and the second already have read it.
Greetings.
