  7.  *    AppleLink:    MINOW
  8.  *
  9.  * Edit History
  10.  *    93.01.09 MM        First public release
  11.  *    93.01.14 MM        Removed Think C stdio dependencies. Added Standard File dialog
  12.  *                    with additional dialog items to allow defining the audit
  13.  *                    selector.
  14.  *    93.01.19 MM        MPW \r is the wrong character. Force <return> on both MPW and
  15.  *                    Think, because this is what the Mac file system requires for
  16.  *                    end of line. (Change is in DisplayAuditFile.c). #if'ed out
  17.  *                    some test calls. Also added error status logging for file I/O
  18.  *                    errors.
  19.  *    93.01.22 MM        Added a preference file that remembers the last audit selector
  20.  *                    parameter and window sizes. Also added error alerts. Moved
  21.  *                    global parameters to DisplayAudit.h.
  22.  *    93.07.09 MM        Reformatted text. Many other changes:
  23.  *                    -- Removed "SimpleTextWindow" -- it was far too simple,
  24.  *                    replacing it with the Log Manager from DTS Catalog Peek.
  25.  *                    -- Added "number of lines to save" to the file dialog (and
  26.  *                    wherever else necessary). Also added number of audit records
  27.  *                    to create.
  28.  *                    -- Revised overall structure so that we can (eventually)
  29.  *                    support multiple Audit records.
  30.  *                    -- Removed fixed "number of audit cycles," replacing it with
  31.  *                    the number of audit records we've created.
  32.  *                    -- Write parameter record whenever it changes. This includes
  33.  *                    changes in the window shape. Note: the parameter record will
  34.  *                    reflect the last window you created. If you create two, only
  35.  *                    the second will be in the parameter record. Actually, the
  36.  *                    "mainline" has been extensively rewritten.
  37.  *
  38.  * This stand-alone application displays the data from a AuditRecord, writing it
  39.  * to a file or the screen. It is not very intelligent.
