/*
 * timemachine_api_create_test.cc
 *
 * An example program demonstrating writing of trace files using the
 * TimeMachine API.  It should be launched from the Windows command prompt
 * or a Unix shell.
 *
 * The file interface is used to create "*.tra" files containing trace data
 * from an external source which are to be viewed and analyzed in
 * TimeMachine.  A "*.tra" file can be loaded into TimeMachine by entering
 * the "traceload filename" command at the MULTI command prompt where
 * "filename" is the name of the "*.tra" file to be loaded.
