docs: Options are usually optional values on the command line and
      have some extra features that arguments don't have.
  
      :param param_decls: the parameter declarations for this option or
                          argument.  This is a list of flags or argument
                          names.
      :param show_default: controls if the default value should be shown on the
                           help page.  Normally, defaults are not shown.
      :param prompt: if set to `True` or a non empty string then the user will
                     be prompted for input if not set.  If set to `True` the
                     prompt will be the option name capitalized.
      :param confirmation_prompt: if set then the value will need to be confirmed
                                  if it was prompted for.
      :param hide_input: if this is `True` then the input on the prompt will be
                         hidden from the user.  This is useful for password
                         input.
      :param is_flag: forces this option to act as a flag.  The default is
                      auto detection.
      :param flag_value: which value should be used for this flag if it's
                         enabled.  This is set to a boolean automatically if
                         the option string contains a slash to mark two options.
      :param multiple: if this is set to `True` then the argument is accepted
                       multiple times and recorded.  This is similar to ``nargs``
                       in how it works but supports arbitrary number of
                       arguments.
      :param count: this flag makes an option increment an integer.
      :param allow_from_autoenv: if this is enabled then the value of this
                                 parameter will be pulled from an environment
                                 variable in case a prefix is defined on the
                                 context.
      :param help: the help string.
