"""
For typical hex dump output formats by the UNIX and GNU/Linux tools ``hexdump``,
``hd``, ``hexcat``, ``od`` and ``xxd``, and the DOS tool ``DEBUG``. For example:
.. sourcecode:: hexdump
00000000 7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 |.ELF............|
00000010 02 00 3e 00 01 00 00 00 c5 48 40 00 00 00 00 00 |..>......H@.....|
The specific supported formats are the outputs of:
* ``hexdump FILE``
* ``hexdump -C FILE`` -- the `canonical` format used in the example.
* ``hd FILE`` -- same as ``hexdump -C FILE``.
* ``hexcat FILE``
* ``od -t x1z FILE``
* ``xxd FILE``
* ``DEBUG.EXE FILE.COM`` and entering ``d`` to the prompt.
.. versionadded:: 2.1
