title: Make: Target name in Rule
body: <p>I have created a <code>Makefile</code> to generate <code>pdf</code> and <code>html</code> for a <code>md</code> file mentioned while invoking make like <code>make a.md</code> should generate <code>a.pdf</code> and <code>a.html</code>, and should not convert other <code>md</code> files present in the directory.</p>
