- * Revision 1.1  1995-12-06 12:41:25  adam
+ * Revision 1.7  1999-07-06 12:28:04  adam
+ * Updated record index structure. Format includes version ID. Compression
+ * algorithm ID is stored for each record block.
+ *
+ * Revision 1.6  1999/05/26 07:49:13  adam
+ * C++ compilation.
+ *
+ * Revision 1.5  1999/02/02 14:51:05  adam
+ * Updated WIN32 code specific sections. Changed header.
+ *
+ * Revision 1.4  1998/03/05 08:45:12  adam
+ * New result set model and modular ranking system. Moved towards
+ * descent server API. System information stored as "SGML" records.
+ *
+ * Revision 1.3  1995/12/11 11:45:55  adam
+ * Removed commented code.
+ *
+ * Revision 1.2  1995/12/11  09:12:51  adam
+ * The rec_get function returns NULL if record doesn't exist - will
+ * happen in the server if the result set records have been deleted since
+ * the creation of the set (i.e. the search).
+ * The server saves a result temporarily if it is 'volatile', i.e. the
+ * set is register dependent.
+ *
+ * Revision 1.1  1995/12/06  12:41:25  adam
  * New command 'stat' for the index program.
  * Filenames can be read from stdin by specifying '-'.
  * Bug fix/enhancement of the transformation from terms to regular
