=head1 NAME
markdown - 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 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>
=head1 OPTIONS
=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>
=item help
Shows this documentation
