- * The public functions simply use char instead of Dict_char to represent
- * search strings. Dict_char is used internally only.
- *
- * Revision 1.8 1995/12/07 11:48:56 adam
- * Insert operation obeys DICT_type = 1 (slack in page).
- * Function dict_open exists if page size or magic aren't right.
- *
- * Revision 1.7 1995/09/04 12:33:32 adam
- * Various cleanup. YAZ util used instead.
- *
- * Revision 1.6 1994/10/05 12:16:52 adam
- * Pagesize is a resource now.
- *
- * Revision 1.5 1994/09/01 17:49:39 adam
- * Removed stupid line. Work on insertion in dictionary. Not finished yet.
- *
- * Revision 1.4 1994/09/01 17:44:10 adam
- * depend include change.
- *
- * Revision 1.3 1994/08/18 12:40:58 adam
- * Some development of dictionary. Not finished at all!
- *
- * Revision 1.2 1994/08/17 13:32:20 adam
- * Use cache in dict - not in bfile.
- *
- * Revision 1.1 1994/08/16 16:26:49 adam
- * Added dict.
