- * Revision 1.8 1994-10-03 17:23:11 adam
+ * Revision 1.21 1996-05-24 14:46:07 adam
+ * Added dict_grep_cmap function to define user-mapping in grep lookups.
+ *
+ * Revision 1.20 1996/03/20 09:35:23 adam
+ * Function dict_lookup_grep got extra parameter, init_pos, which marks
+ * from which position in pattern approximate pattern matching should occur.
+ *
+ * Revision 1.19 1996/02/02 13:43:54 adam
+ * The public functions simply use char instead of Dict_char to represent
+ * search strings. Dict_char is used internally only.
+ *
+ * Revision 1.18 1996/02/01 20:41:06 adam
+ * Bug fix: insert didn't work on 8-bit characters due to unsigned char
+ * compares in dict_strcmp (strcmp) and signed Dict_char. Dict_char is
+ * unsigned now.
+ *
+ * Revision 1.17 1995/12/07 11:47:04 adam
+ * Default pagesize is 4k instead of 8k.
+ *
+ * Revision 1.16 1995/12/06 14:41:13 adam
+ * New function: dict_delete.
+ *
+ * Revision 1.15 1995/10/27 13:59:17 adam
+ * Function dict_look_grep got extra parameter max_pos that upon return
+ * hold length of longest prefix that matches pattern.
+ *
+ * Revision 1.14 1995/10/09 16:18:35 adam
+ * Function dict_lookup_grep got extra client data parameter.
+ *
+ * Revision 1.13 1995/10/06 09:03:51 adam
+ * First version of scan.
+ *
+ * Revision 1.12 1995/09/14 11:53:02 adam
+ * Grep handle function parameter info is const now.
+ *
+ * Revision 1.11 1995/09/04 09:09:51 adam
+ * String arg in dict lookup is const.
+ * Minor changes.
+ *
+ * Revision 1.10 1994/10/05 12:16:58 adam
+ * Pagesize is a resource now.
+ *
+ * Revision 1.9 1994/10/04 12:08:19 adam
+ * Minor changes.
+ *
+ * Revision 1.8 1994/10/03 17:23:11 adam
* First version of dictionary lookup with regular expressions and errors.
*
* Revision 1.7 1994/09/22 10:44:47 adam
*
* Revision 1.4 1994/09/01 17:44:40 adam
* Work on insertion in dictionary. Not finished yet.
