	The 'tape_dup' program, is used to duplicate tapes.  Each tape file
is copied to disk, storing a CRC for each tape record read into an info file,
along with the total files read.  These files are then used to write a new
tape with exactly the same data as the original tape, while performing CRC
data comparisions (ensures the file data has not been corrupted).  You can
also enable a verify option which either verifies the disk data files, or
will verify the disk data with tape file data.

	The Postscript file tape_dup.ps has more details.  There's also a
tape_dup.log and examples files to show you how this all works.

Cheers,
Robin
