=head1 NAME
GO::Parsers::generic_tagval_parser - syntax parsing of GO .def flat files
=head1 SYNOPSIS
do not use this class directly; use GO::Parser
=cut
=head1 DESCRIPTION
This generates Stag event streams from one of the various GO flat file
formats (ontology, defs, xref, associations). See GO::Parser for details
Examples of these files can be found at http://www.geneontology.org
A description of the event streams generated follows; Stag or an XML
handler can be used to catch these events
=head1 GO DEFINITION FILES
These have a suffix .defs or .definitions
