38  * Test program for the JiBX framework. Works with sets of four input
39  * parameters: binding-resource, mapped-class, in-file, comp-file. Unmarshals
40  * documents from files using the binding defined for the mapped class, then
41  * marshals them back out using the same bindings and compares the results to
42  * the comparison file. This form of test is intended for asymmetric bindings,
43  * where the output differs from the input. In case of a comparison error the
44  * output file is left as <i>temp.xml</i>.
