DESCRIPTION
rv is a netsender client using the revid package to perform media collection
and forwarding whose behaviour is controllable via the cloud interfaces
netreceiver and vidgrind.

USAGE
There must firstly be a netsender configuration file under /etc/netsender.conf.
Example:
ma 00:00:00:00:00:01
dk 0
wi
ip V0, T0
op
mp 60
ap 0
tg
hw
sh vidgrind.appspot.com
Revid configuration is controlled by valid variables given values on netreceiver
or vidgrind interface. See revid/config for valid variables.
To run rv simply build and call:
./rv
