  45 <p>This filter ensures that all data written to the DBM file is null
  46 terminated. This is useful when you have a perl script that needs
  47 to interoperate with a DBM file that a C program also uses. A fairly
  48 common issue is for the C application to include the terminating null
  49 in a string when it writes to the DBM file. This filter will ensure that
  50 all data written to the DBM file can be read by the C application.</p>
