+ * $Log: cclqual.c,v $
+ * Revision 1.1  1995-04-10 10:28:20  quinn
+ * Added copy of CCL.
+ *
+ * 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.
