- * Qualifiers are read from a file now.
- *
- * Revision 1.5 1995/02/14 14:12:41 adam
- * Ranges for ordered qualfiers implemented (e.g. pd=1980-1990).
- *
- * Revision 1.4 1995/02/14 13:16:29 adam
- * Left and/or right truncation implemented.
- *

- *
- * Revision 1.2 1995/02/13 15:15:07 adam
- * Added handling of qualifiers. Not finished yet.
