	my ($class, $dir) = @_;
	return bless { dir => $dir }, $class;
}

=head2 new

Sets and returns the directory to search.

=cut

sub dir {
	my ($self, $dir) = @_;
	$self->{dir} = $dir if defined $dir;
	return $self->{dir};
}

=head2 search 

Starts the search and returns a hash of filenames as keys and AudioFile::Info-Objects as values. You may specify a search directory as the first argument 
and also pass a hash with search criteria. See the synopsis for details.

=cut

sub search {
	my $self = shift;
	my $dir  = @_ % 2 == 0 ? '' : shift;
	my $args = {@_};
	my %audio;
			
	for ( File::Find::Rule->file()->name( '*.mp3', '*.ogg', '*.wma' )->in( $dir || $self->dir || '.' ) )
	{
		my $info = AudioFile::Info->new($_);
		
		$audio{$_} = $info
			if $self->pass( $info, $args);
	}
	
	return %audio;
}

=head2 pass

Checks wether a given AudioFile::Info-Object meets given criteria. First argument is the Info-Object, 
second argument is a reference to the criteria hash.

=cut

sub pass
{
	my ($self, $file, $criteria) = @_;
	
	my $crit = Dumper($criteria);
	
	while ( my ($key, $criterium) = each %$criteria ) 
	{
		my $value = $file->$key;
		
		if ( ref($criterium) eq "Regexp" )
		{
			return unless $value =~ $criterium;
		}
		elsif ( ref($criterium) eq "CODE" )
		{
			return unless $criterium->( $file->$key );
		}
		else
		{
			return unless $file->$key eq $criterium;
		}
