- * Revision 1.6 2002/12/19 07:29:47 dhr
- *
- * - avoid (improbable) buffer overflow
- * - suppress prompt after "quit" command
- * - add space to prompt to match aesthetics and man page
- * - elminate a magic number
- *

- *
- * continue renaming dnskey => lwdnsq
- *
- * Revision 1.4 2002/12/12 06:03:41 mcr
- * added --regress option to force times to be regular
- *
- * Revision 1.3 2002/11/25 18:37:48 mcr
- * make sure that we exit cleanly upon EOF.
- *
- * Revision 1.2 2002/11/16 02:53:53 mcr

- * Revision 1.1 2002/10/30 02:25:31 mcr
- * renamed version of files from dnskey/
- *
- * Revision 1.3 2002/10/09 20:14:16 mcr
