- * This is some old code that is not used but that is kept for the moment
- * for debugging purposes.
+ * @todo This is a very dumb data selection keyword writing routine that does
+ *       not take into account any existing keywords. We definitely want a
+ *       more secure logic that checks for existing keywords and possible
+ *       conflicts. But for this prototype software, this code does the job.
