- * $Log: kinput.c,v $
- * Revision 1.16 1996-04-09 10:05:20 adam
- * Bug fix: prev_name buffer possibly too small; allocated in key_file_init.
- *
- * Revision 1.15 1996/03/21 14:50:09 adam
- * File update uses modify-time instead of change-time.
- *
- * Revision 1.14 1996/02/07 14:06:37 adam
- * Better progress report during register merge.
- * New command: clean - removes temporary shadow files.
- *
- * Revision 1.13 1996/02/05 12:30:00 adam
- * Logging reduced a bit.
- * The remaining running time is estimated during register merge.
- *
- * Revision 1.12 1995/12/06 17:49:19 adam
- * Uses dict_delete now.
- *
- * Revision 1.11 1995/12/06 16:06:43 adam
- * Better diagnostics. Work on 'real' dictionary deletion.
- *
- * Revision 1.10 1995/12/06 12:41:22 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
- * expressons in the search engine.
- *
- * Revision 1.9 1995/10/10 12:24:39 adam
- * Temporary sort files are compressed.
- *
- * Revision 1.8 1995/10/04 16:57:19 adam
- * Key input and merge sort in one pass.
- *
- * Revision 1.7 1995/10/02 15:18:52 adam
- * New member in recRetrieveCtrl: diagnostic.
- *
- * Revision 1.6 1995/09/29 15:51:56 adam
- * First work on multi-way read.
- *
- * Revision 1.5 1995/09/29 14:01:43 adam
- * Bug fixes.
- *
- * Revision 1.4 1995/09/28 14:22:57 adam
- * Sort uses smaller temporary files.
- *
- * Revision 1.3 1995/09/06 16:11:17 adam
- * Option: only one word key per file.
- *
- * Revision 1.2 1995/09/04 12:33:42 adam
- * Various cleanup. YAZ util used instead.
- *
- * Revision 1.1 1995/09/04 09:10:37 adam
- * More work on index add/del/update.
- * Merge sort implemented.
- * Initial work on z39 server.
+ * $Id: kinput.c,v 1.45 2002-02-20 17:30:01 adam Exp $
*
+ * Bugs
+ * - Allocates a lot of memory for the merge process, but never releases it.
+ * Doesn't matter, as the program terminates soon after.
