=head1 NAME
Devel::Declare::Interface - Interface to Devel-Declare parsers.
=head1 DESCRIPTION
A higher level interface to Devel-Declare. This is the package you will
interact with the most when using L<Devel::Declare::Parser>.
=head1 SYNOPSIS
package My::Keyword::Method;
use strict;
use warnings;
use Devel::Declare::Parser;
# Look at Exporter-Declare to have most of this done for you.
sub import {
my $class = shift;
my $destination = caller;
enhance( $destination, "make_method", "method" );
no strict 'refs';
*{ $destination . '::make_method' } = \&my_keyword;
}
sub make_method {
my ( $name, $code ) = @_;
my $dest = caller;
no strict 'refs';
*{ $destination . '::' . $name } = $code;
}
1;
=head1 API
The following functions are all exported by default.
=over
=item register_parser( $name )
=item register_parser( $name, $class )
Register a parser under a short name. If $class is not provided caller will be
used.
=item get_parser( $name );
Get the parser class by short name.
=item enhance( $dest_class, $name, $parser );
=item enhance( $dest_class, $name, $parser, $type );
Make $name a keyword in $dest_class that uses $parser. $parser can be a short
name or class name. $type defaults to 'const'.

=head1 FENNEC PROJECT
This module is part of the Fennec project. See L<Fennec> for more details.
Fennec is a project to develop an extendable and powerful testing framework.
Together the tools that make up the Fennec framework provide a potent testing
environment.
The tools provided by Fennec are also useful on their own. Sometimes a tool
created for Fennec is useful outside the greator framework. Such tools are
turned into their own projects. This is one such project.
=over 2
=item L<Fennec> - The core framework
The primary Fennec project that ties them all together.
