        "DESCRIPTION": {
            "content": "This filter ensures that all data written to the DBM file is null terminated. This is useful\nwhen you have a perl script that needs to interoperate with a DBM file that a C program also\nuses. A fairly common issue is for the C application to include the terminating null in a string\nwhen it writes to the DBM file. This filter will ensure that all data written to the DBM file\ncan be read by the C application.\n",
