<p>See File::Spec::Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.</p>

<p>Returns a string representation of the first existing directory
from the following list:</p>

<dd>
<p>The SYS:/temp is preferred in Novell NetWare and the C:\system\temp
for Symbian (the File::Spec::Win32 is used also for those platforms).</p>
</dd>
<dd>
<p>Since Perl 5.8.0, if running under taint mode, and if the environment
variables are tainted, they are not used.</p>

</pre>
</dd>
<dd>
<p>Splits a path into volume, directory, and filename portions. Assumes that 
the last file is a path unless the path ends in '\\', '\\.', '\\..'
or $no_file is true.  On Win32 this means that $no_file true makes this return 
( $volume, $path, '' ).</p>
</dd>
<dd>
<p>Separators accepted are \ and /.</p>
</dd>
<dd>
<p>Volumes can be drive letters or UNC sharenames (\\server\share).</p>
</dd>
<dd>
<p>The results can be passed to <a href="#item_catpath">catpath</a> to get back a path equivalent to
(usually identical to) the original path.</p>
</dd>
<dt><strong><a name="item_splitdir">splitdir</a></strong>

<dd>
<p>The opposite of <a href="../../../lib/File/Spec.html#catdir__">catdir()</a>.</p>

</pre>
</dd>
<dd>
<p>$directories must be only the directory portion of the path on systems 
that have the concept of a volume or that have path syntax that differentiates
files from directories.</p>
</dd>
<dd>
<p>Unlike just splitting the directories on the separator, leading empty and 
trailing directory entries can be returned, because these are significant
on some OSs. So,</p>
</dd>
<dd>

</dd>
<dd>
<p>Yields:</p>
</dd>
<dd>
<pre>
    ( '', 'a', 'b', '', 'c', '' )</pre>
</dd>
</li>
<dt><strong><a name="item_catpath">catpath</a></strong>

<dd>
<p>Takes volume, directory and file portions and returns an entire path. Under
Unix, $volume is ignored, and this is just like catfile(). On other OSs,
the $volume become significant.</p>
