Original commit message from CVS: 2005-06-28 Andy Wingo <wingo@pobox.com> * tests/network-clock-utils.scm (debug, print-event): New utils. * tests/network-clock.scm (*debug*, *with-graph*): New parameters. (*packet-loss*): Unified loss probability. (network-time): Report out-of-band events. * tests/plot-data: Add support for out-of-band events. Hack it into this script instead of passing it down the pipe; should fix this later.
