+=head1 NAME
+
+Bio::Tools::Prediction::Exon - A predicted exon feature
+
+=head1 SYNOPSIS
+
+See documentation of methods.
+
+=head1 DESCRIPTION
+
+A feature representing a predicted exon. This class actually inherits
+off Bio::SeqFeature::Gene::Exon and therefore has all that
+functionality (also implements Bio::SeqFeatureI), plus a few methods
+supporting predicted features, like various scores and a
+significance. Even though these were inspired by GenScan results, at
+least a subset should be generally useable for exon prediction
+results.
+
+=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 one of the Bioperl mailing lists.
+Your participation is much appreciated.

+=head2 predicted_cds
+
+ Title   : predicted_cds
+ Usage   : $predicted_cds_dna = $exon->predicted_cds();
+           $exon->predicted_cds($predicted_cds_dna);
+ Function: Get/Set the CDS (coding sequence) as predicted by a program.
+
+           This method is independent of an attached_seq. There is no
+           guarantee whatsoever that the returned CDS has anything to do
+           (e.g., matches) with the sequence covered by the exons as annotated
+           through this object.
+
+ Example :
+ Returns : A Bio::PrimarySeqI implementing object holding the DNA sequence
+           defined as coding by a prediction of a program.
+ Args    : On set, a Bio::PrimarySeqI implementing object holding the DNA 
+           sequence defined as coding by a prediction of a program.

+=head2 predicted_protein
+
+ Title   : predicted_protein
+ Usage   : $predicted_protein_seq = $exon->predicted_protein();
+           $exon->predicted_protein($predicted_protein_seq);
+ Function: Get/Set the protein translation as predicted by a program.
+
+           This method is independent of an attached_seq. There is no
+           guarantee whatsoever that the returned translation has anything to
+           do with the sequence covered by the exons as annotated
+           through this object, or the sequence returned by predicted_cds(),
+           although it should usually be just the standard translation.
+
+ Example :
+ Returns : A Bio::PrimarySeqI implementing object holding the protein 
+           translation as predicted by a program.
+ Args    : On set, a Bio::PrimarySeqI implementing object holding the protein 
+           translation as predicted by a program.

+
+ Title   : start_signal_score
+ Usage   : $sc = $obj->start_signal_score();
+           $obj->start_signal_score($evalue);
+ Function: Get/Set a score for the exon start signal (acceptor splice site
+           or initiation signal).
+ Returns : 
+ Args    : 
+
+
+=cut
+
+sub start_signal_score {
+    my ($self, $value) = @_;

+    return $self->_tag_value('AccScore', $value);

+=head2 end_signal_score
+
+ Title   : end_signal_score
+ Usage   : $sc = $obj->end_signal_score();
+           $obj->end_signal_score($evalue);
+ Function: Get/Set a score for the exon end signal (donor splice site
+           or termination signal).
+ Returns : 
+ Args    : 
+
+
+=cut
+

+
+ Title   : coding_signal_score
+ Usage   : $sc = $obj->coding_signal_score();
+           $obj->coding_signal_score($evalue);
+ Function: Get/Set a score for the exon coding signal (e.g., coding potential).
+ Returns : 
+ Args    : 
+
+
+=cut
+
+sub coding_signal_score {
+    my ($self, $value) = @_;
