Emulator caveats:

• While the interfaces described below are not expected to change drastically, this facility is still under development and should be considered experimental and subject to change.

• The facility described here has been developed under FreeBSD 2.2.5, and use on other systems has not been tested by the author.

• Because of the currently limited portability of emulation, it is only compiled into nse (build it with ``make nse''), not standard ns.
