 """Print 'Hello world' to the terminal; test links in docstrings.
 
-It is common in RST to use unnamed or anonymous links in text (like
-`here <https://example.com/t-and-c/>`__ and `here
-<https://example.org/co-op-rules.html>`__), but they should have two trailing
-underscores!
-
-You *can* use a `single trailing underscore <https://example.com/links.html>`_
-but it is treated as an implicitly named link. You can use the exact same link
-text and URL again too (`single trailing underscore
-<https://example.com/links.html>`_).
-
-However, the missing second underscore becomes a problem if the same link text
-is used again for another implicitly named link with a *different* URL (e.g.
-missing `single trailing underscore <https://example.com/bad.html>`_).
+Suppose we want to link to the Python_ home page, but have duplicate
+link targets defined?
 
 What happens here?
