How to use the reprozip._pytracer.execute function in reprozip

"You can use --overwrite to replace the existing trace "
                "(or --continue to append\nwithout prompt)")
        elif append is False:
            logger.info("Removing existing trace directory %s", directory)
            directory.rmtree()
            directory.mkdir(parents=True)
    else:
        if append is True:
            logger.warning("--continue was set but trace doesn't exist yet")
        directory.mkdir()

    # Runs the trace
    database = directory / 'trace.sqlite3'
    logger.info("Running program")
    # Might raise _pytracer.Error
    c = _pytracer.execute(binary, argv, database.path)
    if c != 0:
        if c & 0x0100:
            logger.warning("Program appears to have been terminated by "
                           "signal %d", c & 0xFF)
        else:
            logger.warning("Program exited with non-zero code %d", c)
    logger.info("Program completed")

    return c

Runs the command with the tracer using a temporary sqlite3 database, then
    reads it and dumps it out.

    Not really useful, except for debugging.
