* Graphical user interface application based on the AWT (Abstract

* <p>
* <h3>Memory shortage</h3>
* One of the errors experienced most frequently with jiuawt is the
* 'out of memory' error.
* Note that only whoever starts jiuawt can give it more memory by
* giving more memory to the Java virtual machine.
* Example:
* <pre>java -mx300m jiu.jar</pre>
* starts jiuawt and provides it with 300 MB of memory.
*
* <h3>Command line switches</h3>
* <dl>
* <dt><code>--dir DIRECTORY</code>
* <dd>set working directory to <code>DIRECTORY</code>
* <dt><code>--help</code>
* <dd>print help screen to standard output and exit
* <dt><code>--lang LANGUAGE</code>
* <dd>set language to <code>LANGUAGE</code>, where <code>en</code> is English, <code>de</code> is German and <code>es</code> is Spanish
* <dt><code>--system</code>
* <dd>print system information to standard output and exit
* <dt><code>--version</code>
* <dd>print version information to standard output and exit
