    New program, called at prerun time, to generate a virtual topology · a9dea43d

    file in the experiment tbdata directory. This topo file is intended to
    be used on the node to generate inputs to dijkstra and genhostsfile,
    so that routes and /etc/hosts can be generated on the node, rather
    then in tmcd, where it creates a huge bottleneck during experiment
    startup of very large experiments (many 100s of nodes). This topo file is
    slightly more rational then just dumping DB rows like we do from the RPC
    server. For example:
    
    	# nodes: vname,links
    	lonely,link0:10.1.1.2
    	node-1,lan0:10.1.2.2 link0:10.1.1.3
    	node-2,lan0:10.1.2.3
    	node-3,lan0:10.1.2.4
    	# lans: vname,mask,cost
    	lan0,255.255.255.0,1
    	link0,255.255.255.0,1
    
    Usage: gentopofile [-n] pid eid
    
    The file is written as "topomap" in the current directory.  Use the
    -n (impotent) option to dump the topofile to stdout rather writing to
    the file.
