This plugin makes enclosure-href, enclosure-length and
enclosure-type template parameters for the articles with enclosures.

Add the enclosure info to the item template:

    __if_enclosure-href__<div class="enclosure">
    <a href="__enclosure-href__">Enclosure</a> __endif__
    __if_enclosure-type__ __enclosure-type__ __endif__
    __if_enclosure-length__ (__enclosure-length__ bytes) __endif__
    __if_enclosure-href__</div>__endif__

And optionally some formatting, in style.css:

    .enclosure {
            color: gray;
            font-size: small;
            #border-top: 1px solid gray;
            margin: 0;
            padding: 6px;        
    }
