<!-- ===================================================================

   Build file for XPath Api
   Sample usage: build javacc test -Dtest.expr="a/b /a/b /a|b"
   
Setup instructions: 
   Before running an Ant build, you must
   
     - set the JAVA_HOME environment variable to the JDK root directory
   
Build Instructions:   
  To build, run
   ant [antoptions] [targets]
  in the directory where this file is located; you should also be 
  able to use an installation of Ant v1.4.1 or later.
   
  build -projecthelp  will  show a list of supported targets.
   
  Developers: include a description="" attribute in all user-callable targets.
