44  * Test program for the JiBX framework. Works with two or three command line
45  * arguments: mapped-class, in-file, and out-file (optional, only needed if
46  * different from in-file). You can also supply a multiple of three input
47  * arguments, in which case each set of three is processed in turn (in this case
48  * the out-file is required). Unmarshals documents from files using the binding
49  * defined for the mapped class, then marshals them back out using the same
50  * bindings and compares the results. In case of a comparison error the output
51  * file is left as <i>temp.xml</i>.
