Program Example

written in coffeescript.
This is just indicative program to demonstrate functionality . It cannot run as it is.

    ovs = require('ovsdriver')
    ovs.createBridge "sw1", (result) =>
        util.log "Bridge creation " + result                               
    ovs.addInterface "sw1", "veth1",(result) =>
        util.log "AddInterface result", result
