=head1 NAME
goflat - a parser for the Gene Ontology flat-file format
=head1 SYNOPSIS
use Bio::OntologyIO;
# do not use directly -- use via Bio::OntologyIO
my $parser = Bio::OntologyIO->new
( -format => "go",
-defs_file => "/home/czmasek/GO/GO.defs",
-files => ["/home/czmasek/GO/component.ontology",
"/home/czmasek/GO/function.ontology",
"/home/czmasek/GO/process.ontology"] );
my $go_ontology = $parser->next_ontology();
my $IS_A = Bio::Ontology::RelationshipType->get_instance( "IS_A" );
my $PART_OF = Bio::Ontology::RelationshipType->get_instance( "PART_OF" );
=head1 DESCRIPTION
Needs Graph.pm from CPAN.
This is essentially a very thin derivation of the dagflat parser.

Title : new
Usage : $parser = Bio::OntologyIO->new(
-format => "go",
-defs_file => "/path/to/GO.defs",
-files => ["/path/to/component.ontology",
"/path/to/function.ontology",
"/path/to/process.ontology"] );
Function: Creates a new goflat parser.
Returns : A new goflat parser object, implementing L.
Args : -defs_file => the name of the file holding the term
definitions
-files => a single ontology flat file holding the
term relationships, or an array ref holding
the file names (for GO, there will usually be
3 files: component.ontology, function.ontology,
process.ontology)
-file => if there is only a single flat file, it may
also be specified via the -file parameter
-ontology_name => the name of the ontology; if not specified the
parser will auto-discover it by using the term
that starts with a '$', and converting underscores
to spaces
-engine => the Bio::Ontology::OntologyEngineI object
to be reused (will be created otherwise); note
that every Bio::Ontology::OntologyI will
qualify as well since that one inherits from the
former.
