    This Jakarta Ant buildfile is used to build the Java Web Start
    releases of Jskad, Savant, QuillDriver, and the Translation Tool.
    This is separate from build.xml because to use this build file,
    you must have installed the Venus Application Publisher's (Vamp's)
    Ant tasks.  Read the comments of this buildfile to learn more, or
    see 'http://thdltools.sourceforge.net/BuildSystems.html'.

    <!-- Use the Venus Application Publisher's (Vamp's) Ant task to
         create a .war file.  If you use Tomcat or the like to
         distribute, then the WAR is all you need.  If not, you don't
         need the full WAR file.  You in fact need only the JAR file
         inside it.  There is a ${my.app}.jnlp file inside it, too,
         but that file uses macros like $$name and $$codebase, which
         are only appropriate to Tomcat-type environments.

         Thus, you non-Tomcat-users should run 'jar xf
         ${my.app}-web-start.war ${my.app}.jar' to extract the
         signed JAR file and copy the .jar and the
         ${dist}/${my.app}.jnlp file (NOT the one in the WAR) to the
         web server.  (Be sure that the web server has its MIME types
         configured correctly so that the .jnlp file is served as an
         application/jnlp or the like, not text/xml.)

         Yes, it means that we're requiring anyone who wishes to cut a
         JWS release to install vamp.jar, when we could use the
         built-in SignJar task instead for non-Tomcat-users.  BUT,
         this method means that we're ready for a J2EE application
         server framework like the one at Virginia.

         If you change web servers or the location on the web server
         where the JAR and jnlp file are located, you have to edit
         ${my.app}.jnlp.  Note that doing so will mean that users who've
         installed ${my.app} from the old location will NOT be able to
         seamlessly upgrade, so don't do this often.

         To install the Vamp Ant task, visit
         'http://www.vamphq.com/ant.html' and follow the instructions.
         Note that you *CAN* just drop vamp.jar into Ant's 'lib'
         directory with Ant 1.5.1.
