=head1 NAME

B<Biblio::Document::Parser> - document parsing framework 

=head1 DESCRIPTION

Biblio::Document::Parser provides generic methods that should be overriden
by specific parsers. This class should not be used directly, but rather
be overridden by specific parsers.  Parsers that extend the Document::Parser
class should at least override the parse method.

=head1 METHODS

=over 4

=item $docparser = Biblio::Document::Parser-E<gt>new()

The new() method creates a new parser instance. 

=cut

sub new
{
	my($class) = @_;
	my $self = {};
	return bless($self, $class);
}

=pod

=item @references = $parser-E<gt>parse($lines, %options)

The parse() method takes either a content string or an IO::Handle,
and returns an array of reference strings.

=cut

sub parse
{
	my($self, $lines, %options) = @_;
	die "This method should be overridden.\n";
}
