- Delete data:\n\

- BDB_environment BDB_database\n\n\
- Bulk load data from file:\n\
- dlzbdb -f file_to_load BDB_environment BDB_database\n\n\
- Bulk load data from stdin\n\
- dlzbdb -s BDB_environment BDB_database\n\n\
- Add data:\n\
- dlzbdb -a \"dns data to be added\" BDB_environment BDB_database\n\n\
- Export data:\n\
- dlzbdb -e BDB_environment BDB_database\n\n\
- Normally operations can only be performed on an existing database files.\n\
- Use the -n flag with any operation to allow files to be created.\n\
- Existing files will NOT be truncated by using the -n flag.\n\
- The -n flag will allow a new database to be created, or allow new\n\
- environment files to be created for an existing database.\n\n\
