=head1 NAME
X12::Parser::Cf - Perl module for reading X12 configuration files.
=head1 SYNOPSIS
use X12::Parser::Cf;
# Create a X12::Parser::Cf object
my $cf = new X12::Parser::Cf;
# Read/load a cf file
$cf->load ( file => '837_004010X098.cf' );
=head1 DESCRIPTION
X12::Parser::Cf module is created to read the configuration files that
are created for parsing X12 transaction files. This module is used in
the L<X12::Parser> module and is not designed for independent usage.
Note that this module does not do syntax checking of the configuration
file. The user should ensure that he has got the cf file correct.
Read the L<X12::Parser::Readme> man page for details.
The sample cf files provided with this package are good to the best of
the authors knowledge. However the user should ensure the validity of
these files. The user may use them as is at his own risk.
