       build.xml - configuration file used by ant to build projects

       The file build.xml is the default configuration file used by ant to
       determine target to build for a specific project. It can be considered
       the ant equivalent of Makefile..

       The format of ant is XML and for each project a seperate file is
       constructed.  The buildfile consists of one or more tasks. An example
       is given below.

       <project default="compile">

         <target name="compile">
           <javac srcdir="src">


       This example has one target and it is defaulted. The target itself
       consists of one task javac which compiles the files in the src

       Targets can depend on other targets. These dependencies are given by
       the depends attribute of the <target> element.

       A task is a piece of code that is executed.  Ant recognizes built-in
       task, optional tasks, but one can also write new tasks.

       Built-in tasks

       The built-in tasks are: Ant, AntCall, AntStructure, Apply, Available,
       Chmod, Copy, Cvs, Delete, Deltree, Echo, Exec, ExecOn, Fail, Filter,
       FixCRLF, GenKey, Get, GUnzip, GZip, Jar, Java, Javac, Javadoc/Javadoc2,
       Mail, Mkdir, Move, Patch, Property, Replace, Rmic, SignJar, Sql, Style,
       Tar, Taskdef, Touch, TStamp, Unjar, Untar, Unwar, Unzip, Uptodate, War,

       Java   Executes a Java class within the running (Ant) VM or forks
              another VM if specified. Below are some of the attibutes to the
              <java> element:

              classname (required) the Java class to execute

              fork if enabled triggers the class execution in another VM
              (disabled by default)

              jvm the command used to invoke the Java Virtual Machine, default
              is java. The command is resolved by java.lang.Runtime.exec().
              Ignored if fork is disabled.

              Other arguments are classpath, classpathref, maxmemory,
              failonerror, dir and output.

       Javac  Compiles a source tree within the running (Ant) VM.

              srcdir (required) location of the java files

              destdir location to store the class files

              debug indicates whether source should be compiled with debug
              information; defaults to off

              optimize indicates whether source should be compiled with
              optimization; defaults to off

              target generate class files for specific VM version (e.g., 1.1
              or 1.2).

              includes comma-separated list of patterns of files that must be
              included; all files are included when omitted

              excludes comma-separated list of patterns of files that must be
              excluded; no files (except default excludes) are excluded when

              defaultexcludes indicates whether default excludes should be
              used (yes | no); default excludes are used when omitted.

              Other arguments are includesfile, excludesfile, classpath,
              bootclasspath, classpathref, bootclasspathref, extdirs,
              encoding, deprecation, verbose, includeAntRuntime,
              includeJavaRuntime and failonerror.

       A project can have a set of properties, which consist of a name value
       combination. Within tasks they can be used by placing them between "${"
       and "}", as in "${builddir}/classes".

       Built-in Properties

       Ant provides access to all system properties as if they had been
       defined using a <property> task. For example, ${} expands to the
       name of the operating system.

              the absolute path of the project's basedir (as set with the
              basedir attribute of <project>).

              the absolute path of the buildfile.
              the name of the project that is currently executing; it is set
              in the name attribute of <project>.
              the JVM version Ant detected; currently it can hold the values
              "1.1", "1.2" and "1.3".

       The classpath can be set by using the <classpath> element:

         <pathelement path="${classpath}"/>
         <pathelement location="lib/helper.jar"/>
         <fileset dir="lib">
           <include name="**/*.jar"/>
         </fileset> </classpath>
