<h2><a NAME="introduction">Introduction</a></h2>
The pvcs task allows the user of ant to extract the latest edition
of the source code from a PVCS repository. PVCS is a version control system
developed by <a href="http://www.merant.com/products/pvcs">Merant</a>.
<br>
Before using this tag, the user running ant must have access to the commands 
of PVCS (get and pcli) and must have access to the repository. Note that the way to specify
the repository is platform dependent so use property to specify location of repository.
<br>
This version has been tested agains PVCS version 6.5 and 6.6 under Windows and Solaris.

<td VALIGN=TOP WIDTH="78%"><b>Description</b></td>

<td VALIGN=TOP WIDTH="10%"><b>Required</b></td>
</tr>

<tr>
<td VALIGN=TOP WIDTH="12%">repository</td>

<td VALIGN=TOP WIDTH="78%">The location of the repository (see your PVCS
manuals)</td>

<td VALIGN=TOP WIDTH="10%">Yes</td>
</tr>

<tr>
<td VALIGN=TOP WIDTH="12%">pvcsproject</td>

<td VALIGN=TOP WIDTH="78%">The project within the PVCS repository to extract
files from (&quot;/&quot; is root project and that is default if this attribute isn't
specified)</td>

<td VALIGN=TOP WIDTH="10%">No</td>
</tr>

<tr>
<td VALIGN=TOP WIDTH="12%">label</td>

<td VALIGN=TOP WIDTH="78%">Only files marked with this label are extracted.</td>

<td VALIGN=TOP WIDTH="10%">No</td>
</tr>

<tr>
<td VALIGN=TOP WIDTH="12%">promotiongroup</td>

<td VALIGN=TOP WIDTH="78%">Only files within this promotion group are extracted. Using 
both the <i>label</i> and the <i>promotiongroup</i> tag will cause the files in the 
promotion group and with that label to be extracted.
</td>

<td VALIGN=TOP WIDTH="10%">No</td>
</tr>

<tr>
<td VALIGN=TOP WIDTH="12%">force</td>

<td VALIGN=TOP WIDTH="78%">If set to <i>yes</i> all files that exists and are writable are overwritten. Default <i>no</i> causes the files that are writable to be ignored. This stops the PVCS command <i>get</i> to stop asking questions!</td>

<td VALIGN=TOP WIDTH="10%">No</td>
</tr>

<tr>
<td VALIGN=TOP WIDTH="12%">workspace</td>

<td VALIGN=TOP WIDTH="78%">By specifying a workspace, the files are extracted to that location. A PVCS workspace is a
name for a location of the workfiles and isn't as such the location itself. You define the location for a workspace
using the PVCS GUI clients. If this isn't specified the default workspace for the current user is used.</td>

<td VALIGN=TOP WIDTH="10%">No</td>
</tr>

<tr>
<td VALIGN=TOP WIDTH="12%">pvcsbin</td>

<td VALIGN=TOP WIDTH="78%">On some systems the PVCS executables <i>pcli</i>
and <i>get</i> are not found in the PATH. In such cases this attribute
should be set to the bin directory of the PVCS installation containing
the executables mentioned before. If this attribute isn't specified the
tag expects the executables to be found using the PATH environment variable.</td>

<td VALIGN=TOP WIDTH="10%">No</td>
</tr>
    <tr> 
      <td VALIGN=TOP WIDTH="12%">ignorereturncode</td>
      <td VALIGN=TOP WIDTH="78%">If set to <i>true</i> the return value from executing

<h3><a name="nested">Nested Elements</a></h3>

<h3>pvcsproject element</h3>
<p><code>pvcs</code> supports a nested
<code>&lt;pvcsproject&gt;</code> element, that represents a project
within the PVCS repository to extract files from.  By nesting multiple
<code>&lt;pvcsproject&gt;</code> elements under the
<code>&lt;pvcs&gt;</code> task, multiple projects can be
specified.</p>

<h3>Examples</h3>
The following set-up extracts the latest version of the files in the pvcs repository.
<pre>
  &lt;!-- =================================================================== --&gt;
  &lt;!-- Get the latest version                                              --&gt;
  &lt;!-- =================================================================== --&gt;
  &lt;target name=&quot;getlatest&quot;&gt;
    &lt;pvcs repository=&quot;/mnt/pvcs&quot; pvcsproject=&quot;/myprj&quot;/&gt;
  &lt;/target&gt;</ul>
</pre>
<p>Now run:</p>
<code>ant getlatest</code>
<p>This will cause the following output to appear:</p>

This next example extracts the latest version of the files in the pvcs
repository from two projects using nested &lt;pvcsproject&gt; elements.

      &lt;pvcsproject name=&quot;/myprj2&quot;/&gt;
    &lt;/pvcs&gt;
  &lt;/target&gt;</ul>
</pre>
<p>Now run:</p>
