.SH NAME
WWW::RobotRules::DB_File \- Parse robots.txt files using a disk cache
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\&    require WWW::RobotRules::DB_File;
\&    require LWP::RobotUA;
\&
\&    #Create a robot useragent that uses a disk caching RobotRules
\&    $ua = WWW::RobotUA\->new( \*(Aqmy\-robot/1.0\*(Aq, \*(Aqme@foo.com\*(Aq ,
\&          WWW::RobotRules::DB_File\->new( \*(Aqmy\-robot/1.0\*(Aq, \*(Aq/path/cachefile\*(Aq ));
\&
\&    #The just use $ua as usual

.SH DESCRIPTION
.IX Header "DESCRIPTION"
This is a subclass of WWW::RobotRules that uses the DB_File package to
implement disk caching of robots.txt.
.SH METHODS
.IX Header "METHODS"
This is a subclass of WWW::RobotRules, so it implements the same methods
.ie n .IP "$rules = WWW::RobotRules::DB_File\->new(\*(Aqmy\-robot/1.0\*(Aq, /path/cachefile)" 4
.el .IP "\f(CW$rules\fR = WWW::RobotRules::DB_File\->new(\*(Aqmy\-robot/1.0\*(Aq, /path/cachefile)" 4
.IX Item "$rules = WWW::RobotRules::DB_File->new('my-robot/1.0', /path/cachefile)"
This is the constructor. The only difference from the original constructor
from WWW::RobotRules is that you here has to specify a cache file as well.
