=head1 NAME
Bio::Tools::Prints - Parser for FingerPRINTScanII program
=head1 SYNOPSIS
use Bio::Tools::Prints;
my $prints_parser = Bio::Tools::Prints->new(-fh =>$filehandle );
while( my $prints_feat = $prints_parser->next_result ) {
push @prints_feat, $prints_feat;
}
=head1 DESCRIPTION
PRINTScan II is a PRINTS fingerprint identification algorithm.

=head1 FEEDBACK
=head2 Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to
the Bioperl mailing list. Your participation is much appreciated.

=head2 Support
Please direct usage questions or support issues to the mailing list:
I<bioperl-l@bioperl.org>
rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly
address it. Please include a thorough description of the problem
with code and data examples if at all possible.
=head2 Reporting Bugs
