* Compiles NetRexx source files.

* <li>classpath</li>
* <li>comments</li>
* <li>compile</li>
* <li>console</li>
* <li>crossref</li>

* <li>suppressExceptionNotSignalled</li>
* <li>suppressDeprecation</li>
* <li>removeKeepExtension</li>
* </ul>
* Of these arguments, the <b>srcdir</b> argument is required.
*
* <p>When this task executes, it will recursively scan the srcdir
* looking for NetRexx source files to compile. This task makes its
* compile decision based on timestamp.
* <p>Before files are compiled they and any other file in the
* srcdir will be copied to the destdir allowing support files to be
* located properly in the classpath. The reason for copying the source files
* before the compile is that NetRexxC has only two destinations for classfiles:
* <ol>
* <li>The current directory, and,</li>
* <li>The directory the source is in (see sourcedir option)
* </ol>
