+"""Example breaking RST208 with bad option list.
+
+RST supports option lists, blocks of text in the style
+of command line tool help text. This example is based
+on the RST documentation.
+
+-a         Output all.
+-b         Output both (this description is
+           quite long).
+-c arg     Output just arg.
+--long     Output all day long.
+
+-p         This option has two paragraphs in the description.
+           This is the first.
+
+           This is the second.  Blank lines may be omitted between
+           options (as above) or left in (as here and below).
+
+--very-long-option  A VMS-style option.  Note the adjustment for
+                    the required two spaces.
+
+--an-even-longer-option
+           The description can also start on the next line.
+
+-2, --two  This option has two variants.
+Note there is no -3 option!
+
+There ought to be a blank line before that final comment,
+there isn't so this fails validation:
+
+    $ flake8 --select RST RST208/option_list.py
+    RST208/option_list.py:27:1: RST208 Option list ends without a blank line; unexpected unindent.
+
+The end.
