This plugin sets the <code><title></code> tag in the <code><head></code> section of the HTML output.
First page / index page:
<pre><code>title = name of the website | subtitle (short description of the website)
</code></pre>
All other posts and pages:
<pre><code>title = title of the post/page | name of the website
</code></pre>
Notes:
<ul>
<li>The seperator is the default symbol, probably “|”.</li>
<li>Feeds only receive the page/post title and are not modified.</li>
<li>Page numbers are handled too.</li>
</ul>
The code is a very basic copy of:
