- * Revision 1.3  1994-08-18 12:40:58  adam
+ * Revision 1.10  1996-05-24 14:46:04  adam
+ * Added dict_grep_cmap function to define user-mapping in grep lookups.
+ *
+ * Revision 1.9  1996/02/02  13:43:51  adam
+ * 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.
