                  X-Bone Custom Topology
	        ==========================
			Release 3.0 


X-Bone supports custom topologies for X-Bone deployed networks through
custom netlists. Selecting "Custom" as the "Topology" on the Create
Overlay page in the GUI enables a text input box "Custom Netlist". A
URL for netlist, that captures the custom topology, can be specified
in this box. 

The format for the netlist is quite simple - a series of hostname
pairs separated by newlines (See example).  The host names chosen for
the virtual hosts will be those specified in the netlist. The checking 
for pairs is strict, and lines that dont match the pair requirement will 
be discarded. Note that at this time there is no support for comments in
the netlist file.
