		err.log will now have the profiling information, while stdout will
		provide some progress information as Coccinelle moves forward with
		work.

		NOTE:

		DEBUG_FILE support is only supported when using coccinelle >= 1.0.2.

		Currently, DEBUG_FILE support is only available to check folders, and
		not single files. This is because checking a single file requires spatch
		to be called twice leading to DEBUG_FILE being set both times to the same value,
		giving rise to an error.
