 Command-line interface
 ----------------------

 The :mod:`pickle` module can be invoked as a script from the command line,
 it will display contents of the pickle files. However, when the pickle file
 that you want to examine comes from an untrusted source, ``-m pickletools``
 is a safer option because it does not execute pickle bytecode, see
 :ref:`pickletools CLI usage <pickletools-cli>`.

 .. code-block:: bash

   python -m pickle pickle_file [pickle_file ...]

 The following option is accepted:

 .. program:: pickle

 .. option:: pickle_file

   A pickle file to read or ``-`` to indicate reading from standard input.
