This is a development fork of arpwatch. This has been

threaded in order to better deal with the requirements of
multi-interface routers. Information regarding MAC addresses
and interfaces is maintained by the program, and an alert is
issued should a device move between interfaces.  In addition,
event processing has been refactored, and some bugs have been
fixed.
