FreeBSD::Ports and FreeBSD::Ports::Port are modules for parsing FreeBSD's Ports INDEX file and selecting ports that match certain criteria. For example, you might want to list ports maintained by tom@FreeBSD.org sorted alphabetically: my $ports = tie my %port, 'FreeBSD::Ports', '/usr/ports/INDEX'; $ports->maintainer('tom@FreeBSD.org'); $ports->sort('alpha'); foreach my $p (keys %port) { print $p->as_ascii,"\n"; } WWW: http://people.FreeBSD.org/~tom/portpm/
