The Apache Commons Codec package contains simple encoder and decoders for
various formats such as Base64 and Hexadecimal. In addition to these
widely used encoders and decoders, the codec package also maintains a
collection of phonetic encoding utilities.

/**
* Start here! This is the normal entry point into the JAM subsystem.
* JamServiceFactory is a singleton factory which can create a new
* JamServiceParams and JServices. Here is a code sample that demonstrates
* how to use JamServiceFactory.
*
*
* // Get the factory singleton
* JamServiceFactory factory = JamServiceFactory.getInstance();
*
* // Use the factory to create an object that we can use to specify what
* // java types we want to view
* JamServiceParams params = factory.createServiceParams();
*
* // Include the classes under mypackage
* params.includeSources(new File("c:/myproject/src","mypackage/*.java"));
*
* // Create a JamService, which will contain JClasses for the classes found in mypackage
* JamService service = factory.createServiceRoot(params);
*
