 Each command typed interactively is a block.  A script file (a file given as
 standard input to the interpreter or specified as a command line argument to the
 interpreter) is a code block.  A script command (a command specified on the
-interpreter command line with the '**-c**' option) is a code block.  The string
+interpreter command line with the :option:`-c` option) is a code block.  The string
 argument passed to the built-in functions :func:`eval` and :func:`exec` is a
 code block.
