- * When invoked appropriately, it creates a point-to-point network
- * interface with specified parameters. It arranges for packets sent out
- * via that interface by the kernel to appear on its own stdout in SLIP or
- * CSLIP encoding, and packets injected into its own stdin to be given to
- * the kernel as if received on that interface. Optionally, additional
- * routes can be set up to arrange for traffic for other address ranges to
- * be routed through the new interface.
