/**
 * <p>This is Wsdl2java's build file Writer.  It writes the build.xml file.
 * The build.xml file is a ant build file. After run the WSDL2Java and filling
 * the implementation the user just have to cd to the out dir and type
 * and "ant" (of course you must have ant installed). Then the ant will genarate a
 * jar file which named after the wsdl file you used for WSDL2Java.
 * (named after wsdl file ??? I do not get anything better .. the wsdl file may have
 * more than one service ect ... so we can use them.)</p>
 *
 * <p>This build file work on the where it is created ... User can not move the genarated code
 * to another mechine and try to build. (class path is broken). But of cource user can
 * move genarated build file at his will.</p>
 *
 * <p>deploy the webservice using the AdminClient and drop the jar to servlet Container.
 * We might even add another task to deploy the WS as well.</p>
 *
 * <p>This feature can be on and off using the -B option default is off</p>
