Usage: ${0##*/} [--dev ETHERNET_DEV]
Sets configuration options for captagent
Cheifly, it sets up run-time options, by re-writing the configuration.
It then kicks off the captagent script in the foreground.

    --dev -d                Set ethernet device (default: eth0)
    --capturehost -h        Homer SIP capture host (default: capture.homercloud.org)
    --captureport -p        Homer SIP capture port (default: 9060)
    --captureid -i          Homer capture id (default: 2001)
    --capturepassword -w    Homer capture password (default: myHep)
