* This Transform class is the command-line entry point to the Saxon XSLT Processor.

It is possible to subclass this class to provide a customized command line interface. In writing such

The {@link #main} method should instantiate the class and call the {@link #doTransform} method, passing the
* argument list. The argument list can be augmented or modified if required: for example, by adding a -config
* argument to cause the configuration to be initialized from a configuration file.
*
The {@link #initializeConfiguration} method can be implemented to customize the configuration in which
