> This patch introduces a novel query debugger based on the how-provenance information provided by the Provenance component addressed in MRQL-93. The debugger is a GUI based on JTree that allows to navigate through the provenance data associated with the query results in both forward and backward directions. The command to debug an MRQL query e is {{debug  e}} for coarse-grain debugging or {{debug all e}} for fine-grain debugging. The GUI allows you to filter out the output or the input data to reduce the amount of information on screen.
