// In addition to providing tcpdump-like functionality, it can delete,
// delay or duplicate \TCP segments, and inject new segments. Such segment
// manipulation can be controlled via a script.
//
// Script format:
//
// ; ; ...
//
// e.g.:
//
// A2 delete; B3 delete; A3 delay 0.2; A4 copy 1.0,1.2; ...
//
// Where:
// - : A10 means 10th segment arriving from A
// - can be delete, delay or copy:
// - delete: removes (doesn't copy) segment
// - delay : forwards segment after a delay
// - copy ,,,...:
// forwards copies of the segment after the given delays
// (copy 0.5 is the same as delay 0.5)
