       This is a subclass of WWW::RobotRules that uses the AnyDBM_File package to implement persistent
       diskcaching of robots.txt and host visit information.

       The constructor (the new() method) takes an extra argument specifying the name of the DBM file to use.
       If the DBM file already exists, then you can specify undef as agent name as the name can be obtained from
       the DBM database.
