 This option replaces similar functionality from the nmbd lmhosts file.
 
+.SS remote browse sync (G)
+
+This option allows you to setup nmbd to periodically request synchronisation
+of browse lists with the master browser of a samba server that is on a remote
+segment. This option will allow you to gain browse lists for multiple
+workgroups across routed networks. This is done in a manner that does not work
+with any non-samba servers.
+
+This is useful if you want your Samba server and all local clients
+to appear in a remote workgroup for which the normal browse propagation
+rules don't work. The remote workgroup can be anywhere that you can send IP
+packets to.
+
+For example:
+
+       remote browse sync = 192.168.2.255 192.168.4.255
+
+the above line would cause nmbd to request the master browser on the
+specified subnets or addresses to synchronise their browse lists with
+the local server.
+
+The IP addresses you choose would normally be the broadcast addresses
+of the remote networks, but can also be the IP addresses of known
+browse masters if your network config is that stable. If a machine IP
+address is given Samba makes NO attempt to validate that the remote
+machine is available, is listening, nor that it is in fact the browse
+master on it's segment.
+
