14             =head1 NAME
15              
16             Bio::Search::Hit::HMMERHit - A Hit module for HMMER hits
17              
18             =head1 SYNOPSIS
19              
20             use Bio::Search::Hit::HMMERHit;
21             my $hit = Bio::Search::Hit::HMMERHit->new();
22             # use it in the same way as Bio::Search::Hit::GenericHit
23              
24             =head1 DESCRIPTION
25              
26             This is a specialization of L. There
27             are a few news methods L and L. Note that
28             L and L make no sense for this object and will
29             return 0.
