+ * Bug fix: Log preamble wasn't always turned off after recordExtract.
+ *
+ * Revision 1.50 1996/02/12 18:45:36 adam
+ * New fileVerboseFlag in record group control.
+ *
+ * Revision 1.49 1996/02/05 12:29:57 adam
+ * Logging reduced a bit.
+ * The remaining running time is estimated during register merge.
+ *
+ * Revision 1.48 1996/02/01 20:53:26 adam
+ * The temporary per-record keys are compacted a little, and duplication
+ * of the per-records keys are avoided when they are saved in the record
+ * information buffer.
+ *
+ * Revision 1.47 1996/01/17 14:57:48 adam
* Prototype changed for reader functions in extract/retrieve. File
* is identified by 'void *' instead of 'int.
