HexDump 1.00 05-Aug-92, (C) Copyright IBM Corp. 1992.  By Joe Nord

A binary data display and conversion utility, hexdump supports both bin2hex
and hex2bin functionality.  'bin2hex' is pretty self-explainatory.
For 'hex2bin' (-r), hexdump searches the input stream for "nibbles"
converting each pair to a binary output byte.  To facilitate small changes
to binary files, input hex format is compatible with hexdump displayed hex and
characters following a '*' on a line are ignored (for comments).

Syntax:
   HexDump -switches [InfileName]  (output always written to stdout)

Switches:
   -R      Reverse (hex2bin)
   -Sxxx   Start offset (hex)
   -Nxxx   Number of bytes to process (hex)
   -H, -?  Help

Examples "dir | hexdump"
         "hexdump c:\startup.cmd"
         "hexdump -r < myfile.hex > myfile.bin"
         "dir | hexdump | hexdump -r"
