+ *
+ * Revision 1.8  1998/10/13 16:09:54  adam
+ * Added support for arbitrary OID's for tagsets, schemas and attribute sets.
+ * Added support for multiple attribute set references and tagset references
+ * from an abstract syntax file.
+ * Fixed many bad logs-calls in routines that read the various
+ * specifications regarding data1 (*.abs,*.att,...) and made the messages
+ * consistent whenever possible.
+ * Added extra 'lineno' argument to function readconf_line.
+ *
+ * Revision 1.7  1998/02/11 11:53:35  adam

+ * C++ support.
+ *
+ * Revision 1.3  1995/11/01 16:34:58  quinn
