  <!--
  In order to use the Ivy tasks, it is necessary for Ant to be able to find
  the Ivy jar.  If you install the Ivy plugin for your IDE, then the Ivy
  instance in your IDE will handle resolving the necessary dependencies.  If
  you want to be able to run the Ant tasks from the command line, you ned to
  make sure to install the ivy.jar in your ${ANT_HOME}/lib directory so that
  Ant can find it.

  Instructions for installing Apache Ivy can be obtained here:
  
  For use with command-line Ant: http://ant.apache.org/ivy/download.cgi
  For use with an IDE: http://ant.apache.org/ivy/ivyde/download.cgi
  -->

  <!--
  This location is set to that Ant is able to locate the ivy.jar on systems
  (like Linux) that use a package manager but do not install every .jar into
  the system classpath by default (or that don't have a system classpath).
  If the ivy.jar is in ${ANT_HOME}/lib, then it will be found there first
  and this path will be ignored.  If this path does not exist on your system
  its declaration here will not cause an error.
