NAME

       Business::EDI::Spec - Object class for CSV-based U.N. EDI specifications

SYNOPSIS

         use Business::EDI::Spec;

         my $spec = Business::EDI::Spec->new('segment');

DESCRIPTION

       CSV files originally from edi4r are included as part of Business::EDI.  They are used to
       define the many different messages, segements, data elements, composite data elements, and
       codelists that are part of a given version of the U.N. specification.

       The CSV spec files are composed differently for the different structures defined.  So we
       have to parse them differently.
