+ * Revision 1.8 1995/05/11 14:03:57 adam
+ * Changes in the reading of qualifier(s). New function: ccl_qual_fitem.
+ * New variable ccl_case_sensitive, which controls whether reserved
+ * words and field names are case sensitive or not.
+ *
+ * Revision 1.7 1995/04/17 09:31:46 adam
+ * Improved handling of qualifiers. Aliases or reserved words.
+ *
+ * Revision 1.6 1995/02/23 08:32:00 adam
+ * Changed header.
+ *
+ * Revision 1.4 1995/02/14 19:55:12 adam
+ * Header files ccl.h/cclp.h are gone! They have been merged an
+ * moved to ../include/ccl.h.
+ * Node kind(s) in ccl_rpn_node have changed names.
+ *
+ * Revision 1.3 1995/02/14 16:20:56 adam
+ * Qualifiers are read from a file now.
+ *
+ * Revision 1.2 1995/02/14 10:25:56 adam
* The constructions 'qualifier rel term ...' implemented.
