<project name="aspectj-examples" default="spacewar" basedir=".">

    <target name="info" >
      <echo>
  This script builds the AspectJ examples.  

  Relevant targets:
     spacewar        build and run spacewar with debugging (default)
     all             build and run each example
     {example}       build and run any {example} 
                     (use -projecthelp to list {example} names)
     tracing-bc      use AspectJ 1.1 bytecode weaving to build tracing example

  Setup:
     - Run from the doc/examples directory in your AspectJ distribution.
       The tasks in ../../lib/aspectjtools.jar are used automatically.

  Variants:
     - To avoid running (i.e., compile only), define variable "norun"
     - To define a variable, use the Ant -D option - e.g., on Windows:
  
         ant -f build.xml -DJAVA_HOME=c:\jdk1.3.1 -Dnorun=skip
