<h1><a name="description">DESCRIPTION</a></h1>
<p>The <code>DirHandle</code> method provide an alternative interface to the
opendir(), closedir(), readdir(), and <a href="../lib/Pod/perlfunc.html#item_rewinddir"><code>rewinddir()</code></a> functions.</p>
<p>The only objective benefit to using <code>DirHandle</code> is that it avoids
namespace pollution by creating globs to hold directory handles.</p>
<p>

<h1><a name="notes">NOTES</a></h1>
<ul>
<li>
<p>On Mac OS (Classic), the path separator is ':', not '/', and the 
current directory is denoted as ':', not '.'. You should be careful 
about specifying relative pathnames. While a full path always begins 
with a volume name, a relative pathname should always begin with a 
':'.  If specifying a volume name only, a trailing ':' is required.</p>
