26 * Minor changes - removed include of ctype.h.
28 * Revision 1.14 1996/04/09 06:49:18 adam
29 * Traversal of directories doesn't follow symbolic links.
31 * Revision 1.13 1996/03/21 14:50:08 adam
32 * File update uses modify-time instead of change-time.
34 * Revision 1.12 1996/02/05 12:29:55 adam
35 * Logging reduced a bit.
36 * The remaining running time is estimated during register merge.
38 * Revision 1.11 1995/11/20 16:59:44 adam
39 * New update method: the 'old' keys are saved for each records.
41 * Revision 1.10 1995/11/20 11:56:22 adam
42 * Work on new traversal.
44 * Revision 1.9 1995/10/30 13:42:12 adam
