Paragraphs contain text and may contain inline markup:
*emphasis*, **strong emphasis**, `interpreted text`, ``inline
literals``, standalone hyperlinks (http://www.python.org),
external hyperlinks (Python_), internal cross-references
(example_), footnote references ([1]_), citation references
([CIT2002]_), substitution references (|example|), and _`inline
internal targets`.

Paragraphs are separated by blank lines and are left-aligned.
