Python Cookbook recipe 4.6

def flatten(sequence):  #  CONSIDER:  Reconcile with utils...
    for item in sequence:
        if isinstance(item, (list, tuple)):
            for subitem in flatten(list(item)):
                yield subitem
        else:
            yield item

Tx for helping me avoid reading up on it. I just copied it in.

I keep getting "fab not found" etc. when running 'fab command' thru

The long-term solution would be 'bash', '-c', 'yack yack yack' if you
want truly shelly things!
