  <!-- ===================== Property Definitions =========================== -->
  
  <!--

  Each of the following properties are used in the build script.
  Values for these properties are set by the first place they are
  defined, from the following list:

  * Definitions on the "ant" command line (ant -Dfoo=bar compile).

  * Definitions from a "build.properties" file in the top level
  source directory of this application.

  * Definitions from a "build.properties" file in the user's
  home directory.

  * Default definitions in this build.xml file.

  You will note below that property values can be composed based on the
  contents of previously defined properties.  This is a powerful technique
  that helps you minimize the number of changes required when your development
  environment is modified.  Note that property composition is allowed within
  "build.properties" files as well as in the "build.xml" script.
