      Description

      At Mortar we needed an easy way to store/parse a script's map reduce plan. We added an xml output format for the MapReduce plan to make this easier. We also added a flag to keep track of if each store or load was from the original script (and associated with an alias) or if its a temporary store/load generated by Pig.
