How to use the pyflow.src.pyflowTaskWrapper.StringBling function in pyflow

hardFlush(sys.stderr)
        sys.exit(exitval)

    def checkExpectArgCount(expectArgCount) :
        if len(sys.argv) == expectArgCount : return
        badUsage("Incorrect argument count, expected: %i observed: %i\n" % (expectArgCount, len(sys.argv)))


    runid = "unknown"
    taskStr = "unknown"

    if len(sys.argv) > 2 :
        runid = sys.argv[1]
        taskStr = sys.argv[2]

    bling = StringBling(runid, taskStr)

    # send a signal for wrapper start as early as possible to help ensure hostname is logged
    pffp = sys.stderr
    bling.wrapperLog(pffp, "[wrapperSignal] wrapperStart")

    checkExpectArgCount(4)

    picklefile = sys.argv[3]
