Abstract:

    Include file for in-memory DbgPrint function.  Including this file
    will change DbgPrints to a routine which puts the display text in a
    circular buffer in memory.  By default, the text is then sent to the
    console via DbgPrint.  By changing the value of the DigiPrintFlags
    flag, however, the text may be routed to a file instead, thereby
    significantly speeding up the DbgPrint operation.
