  * $Log: extract.c,v $
- * Revision 1.24  1995-11-15 19:13:08  adam
+ * Revision 1.36  1995-11-30 08:34:29  adam
+ * Started work on commit facility.
+ * Changed a few malloc/free to xmalloc/xfree.
+ *
+ * Revision 1.35  1995/11/28  14:26:21  adam
+ * Bug fix: recordId with constant wasn't right.
+ * Bug fix: recordId dictionary entry wasn't deleted when needed.
+ *
+ * Revision 1.34  1995/11/28  09:09:38  adam
+ * Zebra config renamed.
+ * Use setting 'recordId' to identify record now.
+ * Bug fix in recindex.c: rec_release_blocks was invokeded even
+ * though the blocks were already released.
+ * File traversal properly deletes records when needed.
+ *
+ * Revision 1.33  1995/11/27  09:56:20  adam
+ * Record info elements better enumerated. Internal store of records.
+ *
+ * Revision 1.32  1995/11/25  10:24:05  adam
+ * More record fields - they are enumerated now.
+ * New options: flagStoreData flagStoreKey.
+ *
+ * Revision 1.31  1995/11/24  11:31:35  adam
+ * Commands add & del read filenames from stdin if source directory is
+ * empty.
+ * Match criteria supports 'constant' strings.
+ *
+ * Revision 1.30  1995/11/22  17:19:16  adam
+ * Record management uses the bfile system.
+ *
+ * Revision 1.29  1995/11/21  15:01:14  adam
+ * New general match criteria implemented.
+ * New feature: document groups.
+ *
+ * Revision 1.28  1995/11/21  09:20:30  adam
+ * Yet more work on record match.
+ *
+ * Revision 1.27  1995/11/20  16:59:45  adam
+ * New update method: the 'old' keys are saved for each records.
+ *
+ * Revision 1.26  1995/11/20  11:56:24  adam
+ * Work on new traversal.
+ *
+ * Revision 1.25  1995/11/16  15:34:54  adam
+ * Uses new record management system in both indexer and server.
