Anyone have any ideas on how to make a crawler obey robots.txt rules? Heres the crawler so far:

#!/usr/bin/perl

use LWP::Simple;
use HTML::SimpleLinkExtor;
use Data::Dumper;

my $content=get("http://www.yahoo.com");
die "get failed" if (!defined $content);
my $extor = HTML::SimpleLinkExtor->new();
$extor->parse($content);

my @links=$extor->a;

foreach $links (@links) {
print "$links\n";
}
print $content;
[download]

Thanks a bunch!
