General information about Ant and downloads, etc. can be found
at the official website

  http://ant.apache.org

Ant is already installed on pascal.  To use it, you need to have
it in your path and have two environment variables correctly set.

This can be accomplished by the commands:

PATH=$PATH:/usr/local/ant/bin
export ANT_HOME=/usr/local/ant
export JAVA_HOME=/usr/java

It's easiest to include these in your .profile file, so you don't
need to type them every time you open a window.
