            By default, all output is written to the console's standard output stream.
            The <a href="P_log4net_Appender_AnsiColorTerminalAppender_Target.htm">Target</a> property can be set to direct the output to the
            error stream.
            </p><p>
            NOTE: This appender writes each message to the <span class="code">System.Console.Out</span> or 
            <span class="code">System.Console.Error</span> that is set at the time the event is appended.
            Therefore it is possible to programmatically redirect the output of this appender 
            (for example NUnit does this to capture program output). While this is the desired
            behavior of this appender it may have security implications in your application. 
            </p><p>
            When configuring the ANSI colored terminal appender, a mapping should be
            specified to map a logging level to a color. For example:

            The Level is the standard log4net logging level and ForeColor and BackColor can be any
            of the following values:
            <ul><li><strong>Blue</strong> - </li><li><strong>Green</strong> - </li><li><strong>Red</strong> - </li><li><strong>White</strong> - </li><li><strong>Yellow</strong> - </li><li><strong>Purple</strong> - </li><li><strong>Cyan</strong> - </li></ul>
            These color values cannot be combined together to make new colors.
            </p><p>
            The attributes can be any combination of the following:
            <ul><li><strong>Bright</strong> - foreground is brighter</li><li><strong>Dim</strong> - foreground is dimmer</li><li><strong>Underscore</strong> - message is underlined</li><li><strong>Blink</strong> - foreground is blinking (does not work on all terminals)</li><li><strong>Reverse</strong> - foreground and background are reversed</li><li><strong>Hidden</strong> - output is hidden</li><li><strong>Strikethrough</strong> - message has a line through it</li></ul>
            While any of these attributes may be combined together not all combinations
            work well together, for example setting both <i>Bright</i> and <i>Dim</i> attributes makes
            no sense.
