After checking out from the repository, here's how to build.

1. Ensure you have the a suitable version of the JDK installed: either JDK 5.0 or 6 should work. The JDK can be downloaded from http://java.sun.com/javase/downloads/. All other dependencies are included in the repository.

2. Set the JAVA_HOME environment variable to point to the directory where the JDK is installed. For example, on Linux do something like

   export JAVA_HOME=/opt/jdk1.6.0_10
   

   and, on Windows, do something like

   set JAVA_HOME=c:\Program Files\Java\jdk1.6.0_10
   

3. Change your working directory to be root source directory (i.e. the directory containing this file).

4. Run the ant script included in the repository. On Linux, use the command

   ./ant
   

   On Windows, use

   .\ant
   

   This runs the version of ant included in the repository. When the ant script completes, you should find jing.jar and trang.jar in the build directory. You can also tell ant to build the test target, which will build the jars and then run some tests. On Linux, use the command

   ./ant test
   

   On Windows, use

   .\ant test
