[ELECTRON] bash CLI USB/FireWire webcam frame graber ~ VideoScript?

[Ben Rush]

Chris,

Disappointing, but not unexpected. Other then this one step, I have managed
to find a port for os x (10.4.11) for everything else used for this project.
I just happen to have plenty of g4 iBooks that would do the trick. Im not
really up for installing Debian on one of these machines at the moment. My
learning curve just cant take too much more volicity!

Cheers,
Ben Rush
