Advanced use of Ant
===================

The web page for installing Ant indicates

    http://ant.apache.org/manual/index.html

    There are lots of variants that can be used to run Ant. 
    What you need is at least the following:

    * The classpath for Ant must contain ant.jar and any jars/classes
      needed for your chosen JAXP-compliant XML parser.

    * When you need JDK functionality (such as for the javac task or
      the rmic task), then for JDK 1.1, the classes.zip file of the JDK
      must be added to the classpath; for JDK 1.2 or JDK 1.3, tools.jar
      must be added. The scripts supplied with Ant, in the bin
      directory, will add the required JDK classes automatically, if the
      JAVA_HOME environment variable is set.

    * When you are executing platform-specific applications, such as
      the exec task or the cvs task, the property ant.home must be set
      to the directory containing where you installed Ant. Again this is
      set by the Ant scripts to the value of the ANT_HOME environment
      variable.

    The supplied ant shell scripts all support an ANT_OPTS environment
    variable which can be used to supply extra options to ant. Some of
    the scripts also read in an extra script stored in the users home
    directory, which can be used to set such options. Look at the
    source for your platform's invocation script for details.
