<a name="CONSTRUCTOR"></a>
<h3><i>I want the Args to add themselves to the CmdLine...</i></h3>
New constructors have beed added for each <b>Arg</b> that take a
<b>CmdLine</b> object as an argument. Each <b>Arg</b> then <i>add</i>s itself
to the <b>CmdLine</b> object. There is no difference in how the <b>Arg</b>
is handled between this method and calling the <i>add()</i> method directly.
At the moment, there is no way to do an <i>xorAdd()</i> from the constructor.
Here is an example:
<pre>
...
// Create the command line.
CmdLine cmd("this is a message", '=', "0.99" );
// Note that the following args take the "cmd" object as arguments.
SwitchArg btest("B","existTestB", "exist Test B", false, cmd );
ValueArg<string> stest("s", "stringTest", "string test", true, "homer",
"string", cmd );
UnlabeledValueArg<string> utest("unTest1","unlabeled test one",
"default","string", cmd );
// NO add() calls!
// Parse the command line.
cmd.parse(argc,argv);
...
</pre>
