+=head1 NAME
+
+Markdown.pl - Convert Markdown syntax to (X)HTML
+
+=head1 DESCRIPTION
+
+This program is distributed as part of Perl's Text::Markdown module,
+illustrating sample usage.
+
+Markdown can be invoked on any file containing Markdown-syntax, and
+will produce the corresponding (X)HTML on STDOUT:
+
+    $ cat file.txt
+    This is a *test*.
+
+    Absolutely _nothing_ to see here. _Just a **test**_!
+
+    * test
+    * Yup, test.
+    $ Markdown.pl file.txt
+    <p>This is a <em>test</em>.</p>
+
+    <p>Absolutely <em>nothing</em> to see here. <em>Just a <strong>test</strong></em>!</p>
+
+    <ul>
+    <li>test</li>
+    <li>Yup, test.</li>
+    </ul>
+
+If no file is specified, it will expect its input from STDIN:
+
+    $ echo "A **simple** test" | markdown
+    <p>A <strong>simple</strong> test</p>

+=over
+
+=item version
+
+Shows the full information for this version
+
+=item shortversion
+
+Shows only the version number
+
+=item html4tags
+
+Produce HTML 4-style tags instead of XHTML - XHTML requires elements
+that do not wrap a block (i.e. the C<hr> tag) to state they will not
+be closed, by closing with C</E<gt>>. HTML 4-style will plainly output
+the tag as it comes:
+
+    $ echo '---' | markdown
+    <hr />
+    $ echo '---' | markdown --html4tags
+    <hr>
